Stage 1What Gadget Collecting Is

Every household has a drawer where technology goes to wait. A phone with a cracked charging port, a calculator from someone's engineering exams, a cassette player with a tape still inside, a camera nobody has loaded since digital arrived. For years these things are clutter. Then, quite suddenly, they are history, and someone is paying good money for the one your family threw away.

This guide is about collecting that kind of object. "Gadget" is not a precise word, and it is better for it. Here it means a mass-produced device, electronic or precision-mechanical, made for ordinary people to use every day and displaced by something newer within living memory. Cameras, calculators, radios, audio equipment, telephones, game consoles, home computers and watches are the heart of the field. Typewriters, projectors, pagers and clock radios sit at its edges, and collectors wander there freely.

Why people collect them

Most collectors hold several of these motives at once.

• Memory. The radio in a grandparent's house, the first colour television, the console bought after months of pleading. Nostalgia is the largest force in this market and the most predictable: people buy back their childhoods once they can afford to.
• Design. Some gadgets are simply fine objects, and design museums collect them. A pocket radio can show the ideas of an era as clearly as its furniture.
• Technology history. Line up a valve radio, a transistor radio and a phone that plays FM, and you have the history of electronics in three objects.
• Use. Film cameras have found a young audience again, and a well-kept mechanical watch will run for generations. For these collectors, working order is everything.
• Social history. Gadgets record who could afford what, and when. In India, where import rules kept many devices scarce for decades, one imported cassette recorder can carry a family's story of a relative working abroad.

Who this guide is for, and how to use it

It is written for four readers at once: the beginner who has just inherited a box of old electronics, the practising collector who wants to buy better, the specialist who wants model numbers and failure mechanisms, and the general reader who enjoys the stories. The main text serves the first and last. First Steps boxes say what to do today, cheaply; For the Collector boxes carry numbers and market realities; Sidebars tell a story or make an argument.

Part I covers gadget collecting anywhere. Stage 2 explains why the obsolete becomes collectable, and Stages 3 to 5 survey the categories. Stages 6 to 10 are the skills: value, identification, safe testing, repair and fakes. Stages 11 to 13, on storage and preservation, are the most practical part of the guide, and the part to read first if you already own something you care about. Part II, from Stage 14, is the Indian story, closing with where to find gadgets in India today and what the law says.

Two rules run through every stage. Record where each piece came from, what you paid and what condition it arrived in. And never plug in an old mains-powered gadget just to see whether it works. Stage 8 explains why, and it is not an exaggeration: old mains equipment can start a fire, destroy itself or kill.

Stage 2How the Obsolete Becomes Collectable

Nobody sets out to make a collectable calculator. The objects in this guide were made to be used, sold in huge numbers and replaced. The way they turn from waste into collectables follows a pattern clear enough to buy by.

The curve

Most gadgets pass through five phases.

1. New. Expensive, advertised and desired.
2. Used. The price falls as newer models appear, but the object is still useful and changes hands.
3. The trough. The format has died, the network has been switched off, or the replacement is so much better that nobody wants the old one. It is worth less than the effort of selling it, so it is thrown away, stripped or forgotten. Most of the world's stock is destroyed here.
4. Rediscovery. The generation that grew up with the object reaches the age of spare income. Enthusiasts form clubs, share repair notes and scan manuals, and prices on survivors start to move.
5. Collectable. A market forms, with price guides, specialist dealers, a hierarchy of desirable models, and reproductions and fakes.

There is no fixed timetable. As a loose pattern, rediscovery often comes a generation after an object's heyday, somewhere between twenty and thirty-five years: sooner when a format dies abruptly, later when an object stays in use. Some gadgets never recover.

Why the trough creates value

Things become scarce not because few were made but because few were kept. A popular pocket radio may have been made by the million, yet a boxed, working example with its case and earpiece can be genuinely rare, because nobody thought the box worth keeping. Hence a rule that surprises beginners: the more ordinary an object was, the less likely anyone kept a perfect one. Luxury goods were cherished; everyday things were used hard and discarded.

What lifts one survivor above another

• A first, or a famous last. The first of a new kind of device, or the final version of a dying format. Claims to be "the first" are often disputed, so check them.
• Design recognition. The radios and record players Dieter Rams designed for Braun in the 1950s and 1960s are the classic case, and are often compared with digital music players made decades later.
• Cultural weight. The device that changed how people lived, such as the personal stereo.
• A community. Machines with active users stay alive, because people write software for them, make replacement parts and document them. Home computers and consoles benefit most.
• Use. The return of film photography among young people in the 2010s and 2020s pushed up the prices of good film cameras sharply.

Markets can also overheat. In 2021, sealed and professionally graded copies of 1980s and 1990s video games sold at auction for sums that made headlines, and public argument followed about grading and whether prices were being pushed up. Parts of that market later cooled. The old lesson from every collecting field applies: buy what you understand, and what you would be content to own if its price halved.

Stage 3The Categories: Cameras and Watches

Cameras and watches are the precision-mechanical wing of gadget collecting. Both have long-established markets with their own price guides, clubs and repairers, and both crossed from springs to batteries during the twentieth century. That crossing is what makes so many recent examples collectable.

Cameras

Collectors sort cameras by how the photographer sees and focuses.

• Box and folding cameras, from the Kodak Brownie of 1900 onwards. Cheap, plentiful and a good place to learn.
• Rangefinders, focused by lining up two images in a small window. Leica dominates the top of this field, and its cameras are probably the most faked in the world (see Stage 10).
• Twin-lens reflexes, with one lens to view and one to take the picture, looked into from above. The Rolleiflex is the benchmark.
• Single-lens reflexes (SLRs), in which a mirror shows the view through the taking lens and flips up at the moment of exposure. The 35 mm SLRs of the 1960s to 1980s from Nikon, Canon, Pentax, Olympus and Minolta are the backbone of today's user market.
• Compacts, the point-and-shoot cameras of the 1980s and 1990s. The premium ones have become fashionable and expensive.
• Instant cameras, Polaroid above all. Whether a model is a user or a shelf piece depends on whether its film is still made.
• Early digital cameras from the late 1990s and 2000s, once worthless and now wanted by young photographers for their look. Batteries, memory cards and screens are the problems.

What matters is mechanical and optical health: an accurate shutter, a working meter, clear glass and no fungus. Fungus is so serious in Indian conditions that Stage 12 treats it at length.

Watches

Watches divide by what keeps the time.

• Hand-wound mechanical. A mainspring, wound daily at the crown, drives a balance wheel. The everyday standard for most of the twentieth century, and the watch most Indian families remember (see Stage 19).
• Automatic. A mechanical movement wound by a weighted rotor as the wrist moves.
• Quartz analogue. A battery keeps a quartz crystal vibrating at a precise frequency, and a tiny stepping motor moves the hands. Far more accurate than a mechanical watch, and far cheaper to make.
• Digital. Red LED displays in the early 1970s, lit only when a button was pressed, then liquid-crystal displays that showed the time continuously, followed by calculator, databank and game watches.

The recently obsolete end of the field is rich and affordable: LED watches, 1980s digitals, early quartz models and everyday mechanical watches from makers that no longer exist. The originality questions of luxury watches apply just as sharply at lower prices. A replaced dial, hands or crown can halve a watch's value.

Stage 4The Categories: Radios, Audio and Telephones

These three share one history, sound carried by electricity, and one danger, the mains supply. Between them they offer a wide choice at every price.

Radios

Valve radios, called tube radios in America, dominated from the 1920s to the 1960s. Glass valves amplified the signal and glowed as they worked. The sets were heavy, housed in wood or Bakelite, and ran internally at hundreds of volts. Some cheaper designs, known as AC/DC or universal sets, connected the metal chassis directly to one side of the mains, so that parts a person can touch may be live. Read Stage 8 before one goes anywhere near a socket.

Transistor radios arrived in the mid-1950s. The American Regency TR-1 of 1954 is generally counted the first sold commercially, and Japanese makers, Sony among the earliest, soon led the world. Small, cheap and battery-powered, the transistor radio carried broadcasting into fields, kitchens and shops, and in Indian English a portable radio is still simply "a transistor". Collectors seek early sets, colourful pocket radios, multiband receivers for shortwave listening, and design pieces.

Audio

• Record players and turntables, from wind-up gramophones to the direct-drive decks of the 1970s.
• Reel-to-reel tape recorders, heavy and mechanically complex.
• Cassette equipment. The compact cassette, introduced by Philips in 1963, became the most portable music format of its age. Top home decks command high prices; personal stereos are the popular end.
• Radio-cassette recorders, the two-in-ones that filled homes across Asia and the Gulf (see Stage 16).
• Hi-fi separates, especially the heavy silver-fronted amplifiers and receivers of the 1970s.
• Digital portables: CD players from the mid-1980s, Sony's MiniDisc from 1992, and hard-disk and flash music players from around the turn of the century.

Loudspeakers need a note of their own. Many have foam surrounds around the cone that crumble with age. Replacing them is routine, but it must be declared when selling.

Telephones

• Fixed-line telephones: rotary-dial sets, push-button phones, cordless handsets and answering machines. Many were made for national telephone services, which gives them a strongly national character.
• Early mobiles: the car phones that came first, then handheld "bricks", with Motorola's DynaTAC, on sale from 1983, the first of them.
• Feature phones: the candybar, flip and slider phones of the late 1990s and 2000s. Nokia dominated much of the world, India included.
• Pagers and personal digital assistants, the pocket organisers the smartphone swallowed.
• Early smartphones, especially first-generation models and designs that led nowhere.

Networks complicate phone collecting. Many countries have switched off the 2G or 3G networks older phones need, so "working" may mean only that a phone powers on. The battery pack is the hazard, as Stage 11 explains.

Stage 5The Categories: Calculators, Home Computers and Consoles

The gadgets that compute are the youngest part of the field and the fastest growing. They also have the most active communities, which keep old machines running long after their makers have gone.

Calculators

Before electronics came mechanical calculators, and the most famous is the Curta, a hand-cranked cylinder small enough to hold in one hand (see the sidebar). Electronic desktop calculators arrived in the early 1960s, and within a decade pocket models had followed. Collectors usually follow the display.

• LED (light-emitting diode): glowing red digits, often under small magnifying bubble lenses, in pocket calculators of the early and mid-1970s. They drained batteries quickly.
• VFD (vacuum fluorescent display): blue-green digits in a flat glass tube, bright and power-hungry, common in desktop and some pocket models.
• LCD (liquid-crystal display): grey or black digits that sip power. LCDs, and later solar cells, made the calculator the cheap, thin object everyone knows.

Hewlett-Packard's HP-35 of 1972, the first scientific pocket calculator, made the slide rule obsolete within a few years and is a key piece. Programmable and graphing calculators, card-thin novelty models and calculator watches all have their followers. Dead rechargeable battery packs and failed display connections are the usual faults.

Home computers

The personal computer began as a hobbyist's kit in the mid-1970s. By 1977 ready-made machines such as the Apple II, the Commodore PET and the Tandy TRS-80 were on sale, and the 1980s brought a flood of cheap 8-bit home computers that plugged into a television: the Sinclair ZX Spectrum, the Commodore 64, the BBC Micro, the MSX machines and many more. IBM's PC of 1981 set the pattern office machines followed, and the Apple Macintosh of 1984, the Commodore Amiga and the Atari ST brought graphical screens and mice into homes.

Home computer collecting is regional. A machine that was everywhere in Britain may be unknown in America, and the reverse. Completeness matters greatly: power supply, leads, manuals, and software on cassette, floppy disk or cartridge. Power supplies and ageing components are the weak points (see Stages 8 and 11).

Consoles

Home video game consoles began with the Magnavox Odyssey of 1972. The Atari VCS of 1977 made cartridge games a mass market, and Nintendo's Famicom, sold abroad as the NES, rebuilt that market after the American crash of 1983. Nintendo's Game Boy of 1989 and Sony's PlayStation, launched in Japan in 1994, each defined a generation.

Regional variants matter, because Japanese, American and European versions often differ in shape, name, television standard and value. Many cartridges that save games contain a small battery that eventually dies. Clones and reproductions are everywhere (see Stage 10), and in India a clone was, for many children, the only console they knew (see Stage 18).

Stage 6What Drives Value: Working, Display, Boxed and Complete

Two examples of the same model can differ in price tenfold or more. The difference is almost always function, condition and completeness, and learning to read those three is worth more than any price guide.

Working or display

Gadget buyers fall into two camps. Users want a camera to shoot film, a console to play, a watch to wear. Display collectors want an object that looks right on a shelf. The same piece can be worth very different sums to each. For users, a cosmetically worn camera with an accurate shutter beats a pristine one with a sticky shutter. For display collectors, a beautiful non-working example may be perfectly acceptable, and some very high-grade pieces are best never powered again.

The honest middle term is serviced: tested, cleaned and repaired by a named technician, with the work described. A properly serviced working gadget usually sells for more than an unserviced one, and the service record adds value of its own.

Beware the word untested. It usually means the seller tried it and it did not work, or knows why it will not. Price anything untested as broken.

Completeness

A gadget left the factory as a set: the device, its box, inner packaging, manuals, warranty card, accessories, cables, charger and sometimes a dealer's receipt. Each piece that survives adds value, and the box often adds most, because it was the first thing thrown away.

For consoles and games, the box and paper inserts can double a price or more. For cameras, the original lens cap, case and instruction book matter. For watches, the box and filled-in guarantee card, known together as "box and papers", support originality. For phones, a box whose label matches the handset's IMEI, the unique identity number of a mobile handset, turns a phone into a collector's phone.

Matching matters too. A box from a different colour variant or serial range is worth less than the right one, and mismatched sets are sometimes passed off as original.

Condition and the other drivers

Most categories use a cosmetic ladder from mint to poor, applied loosely. Some sellers use inflated scales, where "excellent" with several plus signs describes what an older dealer would call good, so judge from photographs, not words. Beyond condition, value moves with:

• Variant: colour, region, limited edition or early production run.
• Provenance: a documented history, a single owner, a known collection.
• Originality: unmodified, with original parts and finishes (see Stage 9).
• Fashion: early digital compacts were worthless until young photographers wanted their look.

Stage 7Identification and Model Research

A gadget tells you a surprising amount about itself if you look before you search. The habit is the same as in any collecting field: note everything the object says, then find sources, then compare them.

Read the object

Start with the rating label or model plate, usually on the underside, on the back, inside the battery compartment or behind a removable panel. It gives the maker, model number, voltage and power, and often a serial number and country of manufacture. On cameras, the model name is on the front or top plate and serial numbers are engraved on the body and, separately, on the lens. On watches, model and reference numbers are often stamped inside the case back, which only a watchmaker should open.

Then note everything else: logos and their style, which changed over the years; certification marks; voltage selectors; plug type; the language on the controls; stickers from dealers and repairers; and any marks left by previous owners.

Dating from the inside

Electronic components often carry their own dates. Many integrated circuits are printed with a four-digit code of year and week, so that 8534 would mean the thirty-fourth week of 1985. Capacitors, speakers and circuit boards may carry similar codes, though conventions vary by maker. The latest date found on the components gives the earliest date the gadget could have been assembled. Only a technician should open mains equipment to look.

Serial numbers date production in many categories, because collectors have compiled tables linking serial ranges to years for the major camera, lens and watch makers. Seiko, for example, long used serial numbers whose first digit gives the last digit of the year and whose second gives the month. Such tables are usually built from surviving examples rather than factory records, and they disagree at the edges.

Variants and revisions

One model name can hide many versions: different circuit boards, running changes in production, colour variants and regional editions. Regional differences are the commonest trap. A console may be built for a different television standard, a radio for different frequency bands, a camera sold under another name in another market, and a mains gadget built for 100 or 120 volts rather than India's 230. Plugging one of those into an Indian socket without a suitable step-down transformer is likely to destroy it.

Where model knowledge lives

• Original documents: user manuals, service manuals with circuit diagrams, sales brochures, dealer catalogues and price lists.
• Period magazines on photography, hi-fi, computing and gaming, whose reviews and advertisements give launch dates and prices.
• Collector clubs and societies, which often keep archives, registers and repair notes.
• Enthusiast databases and archives online, including very large collections of scanned manuals and catalogues. Invaluable, but often copied from one another.

Stage 8Before You Pay: Inspecting and Testing Safely

Testing is where collectors lose money, damage rare objects and occasionally hurt themselves. The aim is to learn as much as possible about a gadget's condition without applying power until it is safe to do so.

The danger in an old mains gadget

Do not plug in an old mains-powered gadget to see whether it works. For a beginner this rule has no exceptions, and the reasons are specific.

• Electrolytic capacitors deteriorate after years unused. Powered suddenly, they can short, overheat, leak or burst.
• Paper and wax capacitors in old valve radios absorb moisture and become leaky, overloading other parts.
• Mains filter capacitors of some older types crack with age and can fail with smoke when first powered.
• Selenium rectifiers, used in some older sets, can burn out and release toxic fumes with a strong, foul smell.
• Cables and insulation go brittle, crack and expose live wire. Rodents chew them.
• Live chassis. In AC/DC sets the metal chassis, and sometimes the screws in the knobs, may be connected to the mains.
• Wrong voltage. Equipment built for 100 or 120 volts can be wrecked by India's 230 volts.
• Picture tubes. Televisions and monitors with a cathode-ray tube (CRT) generate many thousands of volts, and the tube can hold a dangerous charge long after it is unplugged. Never open one.

Mains electricity kills. The first power-up of a long-idle valve radio, television, amplifier or old computer power supply is a job for a qualified technician, who will inspect it, replace suspect parts, and bring it up gradually using current-limiting equipment. If you want to learn this work, learn it from someone qualified, and start on low-voltage battery equipment.

What you can safely check unpowered

• Smell for burning or chemical odours, and look through the vents with a torch for bulging or leaking capacitors, scorch marks, loose parts and nests.
• Tilt gently and listen for loose screws or broken pieces.
• Inspect the cable and plug for cracks, taped repairs and exposed wire.
• Open battery compartments, check for corrosion (see Stage 11), and remove any old batteries now.
• Read the voltage on the rating label and any selector switch.

Testing by category

Battery gadgets. Fit fresh batteries only once the compartment is clean and dry. A swollen lithium-ion pack in a phone, laptop or camera is a fire risk: do not charge it, do not puncture it, and take it to an e-waste collection point.

Cameras. With no film loaded, open the back, set the slowest speeds and fire the shutter while looking through it at a light, listening for timings that sound wrong. Check the aperture blades for oil. Shine a torch through the lens and look for haze, scratches, separation and the fine threads of fungus. Press the foam light seals: sticky black residue means they need replacing.

Watches. Wind a mechanical watch fully, set it, and check it over a day. Do not open the case back yourself.

Computers and consoles. Have the original power supply checked before use, or use a known-good modern replacement of the correct specification. Never insert or remove a cartridge with the power on.

Phones. Check that the IMEI matches the box, and that the phone is not reported stolen or locked to a previous owner's account.

Buying at a distance

Ask for what you would check in person: photographs of the rating label and serial number, the battery compartment, the display switched on, and the lens lit from behind; a short video of the function that matters; and a clear returns policy. Ask how it will be packed, with batteries removed and lenses capped. A seller who will not answer these questions has answered them.

Stage 9Repair versus Originality

Every gadget collector eventually faces the same question. The object in front of you does not work, or works badly. Do you repair it, and if so, how far can you go before it stops being the thing you bought?

Three approaches

• Conservation stabilises an object as it is. Batteries come out, corrosion is halted, the object is cleaned gently and stored well, and nothing original is replaced. It suits rare pieces and objects valued as historical evidence.
• Restoration to working order replaces what has failed so that the gadget works again: belts, light seals, capacitors, lubricants, batteries. Most collectors of cameras, audio, computers and consoles accept it, provided it is done well and declared.
• Modification changes the object beyond its original specification: new screens, modern video outputs, memory cards in place of disk drives, new shells. It can make a gadget far more usable. It also makes it something else, and must be described as such.

None of these is wrong. The mistake is doing one while claiming another.

Consumables and identity

The workable principle is that consumable parts may be replaced, but original identity should not be. Belts, light seals and batteries are designed to wear out. Capacitors are a harder case: replacing ageing electrolytic capacitors, called recapping, is standard practice for keeping electronics alive, though some specialists keep unusual original components where they are safe.

Cases, dials, labels, knobs, badges and finishes are the object's identity. Repainting a radio cabinet, reprinting a watch dial, re-covering a camera with modern leatherette or polishing marks out of a plastic case all reduce value to a serious collector, even when the result looks better.

Rules for any repair

1. Reversible where possible. Choose repairs a later owner could undo.
2. Keep what you remove. Bag and label every original part taken out, and keep the bag with the object.
3. Record everything: date, work done, parts used and who did it.
4. Declare it when selling. An honest description protects your reputation and the next owner.
5. Know when to stop. Rare pieces, mains equipment and anything with a picture tube belong with a professional.

Safety at the bench

Soldering flux gives off irritating fumes, so work in moving air. Older solder contains lead: wash your hands and keep food and drink off the bench. Isopropyl alcohol, the standard electronics cleaner, is flammable. Many solvents craze clear plastics instantly, so test on a hidden spot first. Never use general-purpose penetrating sprays in camera shutters, watch movements or tape mechanisms, where they spread and gum up.

Stage 10Fakes, Franken-Builds and Misdescriptions

Gadget fakes are rarely made from nothing. Most are real objects altered to look like something more valuable, assembled from several sources, or simply described as better than they are. Knowing the common patterns protects you from most of them.

The main kinds

• Re-engraved and re-badged objects: a cheap genuine camera or watch altered to pass as a rarer one.
• Franken-builds: gadgets assembled from several donors. Honestly described, a franken-build is a useful working object; sold as original, it is a fraud.
• Reproductions: new copies of scarce cartridges, boxes, manuals and labels, often sold openly as reproductions and later resold without the word.
• Reseals: opened or emptied items rewrapped to look factory-sealed.
• Redials and refinishes: watches with reprinted dials, radios with reprinted tuning scales.
• Clones: unlicensed copies made at the time, such as the Famicom-compatible consoles sold across Asia, collectable in their own right but not as the original.
• Misdescriptions: "rare", "prototype", "fully working" and "no fungus" are claims, not facts.

Cameras

The classic fake is the Leica. Soviet rangefinders, which followed Leica's design closely, were for decades re-engraved with Leica names, often with invented wartime German military markings, and sold to tourists and collectors (see the sidebar). The engraving is usually too crisp or wrongly placed, the lettering is wrong, and the serial numbers do not fit genuine ranges. Lenses swapped between bodies and cameras with replaced top plates are subtler. For any expensive camera, check the serials against published registers and have it inspected.

Watches, games and the rest

Watches. Redials are the commonest problem: a worn dial is refinished or replaced with a newly printed one, usually with small errors in the logo, lettering or luminous markers. Frankenwatches combine a case, movement and dial from different sources. India has its own version of this problem with refurbished HMT watches (see Stage 19).

Consoles and games. Reproduction cartridges often have labels with slightly wrong colours or print quality, and modern circuit boards inside. Handheld consoles are commonly rebuilt in new shells with modern screens and sold as original. Collectors have published guides to what genuine factory seals looked like for many publishers.

Computers, audio and phones. Watch for swapped keyboards and boards, repainted colour variants, refurbished phones sold as new, counterfeit batteries, and replacement loudspeaker drivers in cabinets described as original.

Storage and Preservation

Stage 11Preservation: What Decays Inside an Idle Gadget

An old gadget on a shelf is not resting. Its batteries may be leaking, its capacitors drying, its plastics reacting with light and air, and its rubber turning to tar. This stage takes these enemies one by one, with the mechanism of each, because knowing why something decays tells you what to do about it. Stage 12 covers lenses, media and paperwork; Stage 13 the conditions, climate and routine that slow it all down.

Batteries: the first enemy

Remove the batteries. From everything, every time, before storage. It is the single most valuable preservation step in this guide.

Alkaline cells contain potassium hydroxide, a strongly caustic electrolyte. As cells age, and especially once they are flat, it escapes through the seals. In air it forms the familiar white crystalline crust, and it attacks the metal contacts, turning them blue-green or black. Worse, it creeps along springs and wires and across circuit boards, sometimes under the protective coating, where it eats copper tracks out of sight. Cheaper zinc-carbon cells leak too, with different chemistry and much the same result. A radio can be ruined by cells left in "for convenience" through a single monsoon.

• Cleaning light corrosion. Wear gloves and eye protection. Brush loose crust off dry, over paper. Alkaline residue is neutralised by a cotton bud barely damp with white vinegar or lemon juice; follow with isopropyl alcohol and let it dry completely, keeping liquid out of the gadget. If corrosion has spread beyond the compartment into wiring or the circuit board, stop and take it to a technician.
• Button cells in watches, calculators and cameras leak in the same way on a smaller scale. Many collectors have them removed from quartz watches before long storage, but opening a case back is a watchmaker's job, because it can admit dust and damage the seals.
• Backup cells soldered to circuit boards are the hidden threat in some home computers and other equipment of the 1980s and 1990s. Rechargeable nickel-cadmium cells, often small blue cylinders, leak electrolyte that destroys the board around them. Having a technician remove them before they leak is standard advice for the machines known to carry them.
• Save-game cells. Many game cartridges keep saves in memory powered by a lithium coin cell. These rarely leak badly, but they go flat eventually and the saves vanish. Back up any save you care about before the cell is replaced.
• Lithium-ion and lithium-polymer packs in phones, laptops, music players and cameras age even unused. Stored full or completely flat they degrade faster, and storage at roughly half charge in cool conditions is the usual guidance. A pack left flat for years may be unsafe to recharge. A swollen pack is a fire risk: do not charge, press or puncture it, keep it away from anything flammable, and take it to an e-waste collection point. Removing a glued-in swollen battery is a job for a professional.

Capacitors and long-idle electronics

Aluminium electrolytic capacitors, the small cylinders on almost every circuit board, depend on a thin oxide layer and a liquid or paste electrolyte. Over decades the electrolyte dries, and in long storage without power the oxide layer can degrade. Suddenly powered, such a capacitor may pass too much current, overheat and fail, which is one reason Stage 8 forbids the "just plug it in" test.

Some capacitors leak. Small surface-mount electrolytic capacitors of the late 1980s and 1990s are notorious for spilling corrosive electrolyte onto boards, and certain handhelds, computers and CD equipment of that period are known for it. In the early 2000s, capacitors made with faulty electrolyte failed in huge numbers in computer motherboards and monitors, a problem remembered as the capacitor plague. The signs are domed or split tops, brown residue and a fishy smell. In valve radios, paper and wax capacitors absorb moisture and begin to conduct. These are expected failures, and the remedy is replacement by someone competent.

Plastics: yellowing, stickiness, brittleness and off-gassing

Yellowing. Many light-coloured plastics, especially the ABS used for computers, consoles and keyboards, yellow with age. The usual explanation involves brominated flame retardants in the plastic reacting under ultraviolet light and heat. Direct sun yellows a case in months, and even indoor daylight works slowly, which is why one keyboard can show several shades.

Sticky coatings. The rubbery soft-touch finish on many cameras, remote controls, mice and phones from the 1990s onwards breaks down by hydrolysis, a reaction with moisture in the air, and turns tacky and then gummy. Heat and humidity speed it up, and it cannot be reversed. Rubber grips and feet can go sticky in the same way, or harden and crack.

Embrittlement. Plastics lose flexibility with age. A clip that held a battery door for twenty years snaps when opened, and cases crack at the screw posts. Open old gadgets slowly and never force a clip. Foam is worst of all: the polyurethane foams in packaging inserts, light seals, headphone pads and speaker surrounds crumble to dust or collapse into black goo.

Off-gassing. Decaying materials give off vapours. Ageing PVC releases acidic compounds, some early cellulose-based plastics smell of vinegar as they release acetic acid, and rotting foam and rubber have their own emissions. Sealed in a box, these build up and attack neighbours: metal corrodes, paper stains and other plastics degrade faster. Isolate anything that smells, and give it air.

Rubber belts and mechanisms

Cassette decks, personal stereos, video recorders, turntables, CD drawers and some disk drives depend on rubber belts and small rubber wheels called idler tyres. Rubber ages whether used or not. Belts stretch and slip, or melt into a black, sticky residue that smears through the mechanism. Treat them as consumables, and when one has melted, clean the residue off every pulley before fitting the new belt.

• Never store a cassette deck with a tape inside or with play or pause engaged. The rubber pinch roller takes a flat spot and the tape stretches.
• Engage transit screws and locks on equipment that has them, such as some turntables and reel-to-reel recorders, before moving or storing it.
• Grease in camera focusing mounts, shutters and watch movements stiffens and gums with age. Cleaning and relubrication is a service job.

Screens and displays

• Liquid-crystal displays are damaged by heat and ultraviolet light; a calculator left in the sun can develop dark patches. Their polariser film also decays in heat and humidity, producing brown blotches that spread from the edges.
• Display connections usually fail first. Many LCDs are joined to their boards by rubbery conductive strips or heat-sealed ribbon cables, so missing segments or lines often mean a connection fault, not a dead screen.
• Backlights in older laptops and monitors are fluorescent tubes that dim with age and contain a little mercury; treat a broken one as hazardous waste.
• Vacuum fluorescent displays and early OLED screens dim and burn in with use, so never leave equipment switched on for show.
• Cathode-ray tubes burn in from static images and are fragile at the neck. Carry them by the body, two people to a set, keep magnets away, and never open one.

Exercising working gear

Serviced, known-good gadgets benefit from gentle, regular use: shutters left unfired for years stick, lubricants settle, and working electronics generally fare better for occasional power. Every few months, fire a camera's shutter a few times at each speed, run a cassette deck for twenty minutes, wind a mechanical watch, and bring a phone battery back to about half charge.

Two cautions. Exercise only equipment known to be safe, never an unserviced mains set. And every use is also wear, so exercise a rare, perfect piece lightly and less often than a camera you shoot with.

Stage 12Preservation: Lens Fungus, Media, Manuals and Boxes

Some of what a gadget collector keeps is not electronic at all. Glass grows fungus, tapes and discs lose their data, and the paper that came in the box is often more fragile than the device. Each needs its own care.

Lens fungus: the Indian camera's great enemy

Fungal spores are everywhere. Given sustained humidity, still air and darkness, they grow on lens surfaces and between the elements inside, feeding on the organic traces every lens carries: fingerprints, dust, pollen and lubricant vapour. The Indian monsoon supplies those conditions for months, and a camera bagged in June can come out in October with a colony inside the lens.

Fungus looks like fine threads, webs, ferns or spots, best seen with a torch shone through the lens. It is not merely cosmetic: its acids etch the coatings and in time the glass, leaving permanent marks that scatter light. And it spreads to other lenses kept in the same bag or cupboard.

Keep fungus separate in your mind from two other faults. Haze is a milky film from evaporated lubricants, usually cleanable. Separation is the failure of the cement between glued elements, seen as a rainbow sheen or a whitish patch at the edge, and it needs a specialist. Binoculars, projectors, camcorders, microscopes and scanners suffer all three.

Prevention is the whole answer, because treatment is uncertain.

• Keep relative humidity below about 50% where cameras and lenses live, and never let it sit above about 60–65% for long.
• Give lenses air and light. Use them regularly, and in dry weather leave them out of cases for a while, but never point a lens at the sun, which can burn the shutter or sensor behind it.
• Store cameras out of leather cases and camera bags, which hold moisture. Use lidded boxes with silica gel, or a dry cabinet (see Stage 13).
• Keep caps on both ends of lenses, clean fingerprints off promptly, and isolate any lens with fungus from the rest.
• Let equipment warm up inside a closed bag before unpacking it after moving from an air-conditioned room into humid air, or condensation will form on and inside the glass.

Treatment belongs with a camera technician. Surface fungus caught early can often be cleaned away, and a technician can open the lens safely. Home remedies involving household chemicals, or opening a lens without the right tools, usually add scratches, damage coatings and leave the lens out of alignment. Once coatings are etched, the damage is permanent, and it must be declared when selling.

Magnetic media

Tape, whether audio, video or reel, holds magnetic particles on its surface with a binder. In some tapes, particularly certain types of the 1970s and 1980s, the binder absorbs moisture and breaks down, called sticky-shed syndrome: the tape squeals, drags and sheds onto the heads. Archives recover such tapes by controlled low-temperature baking before copying, a specialist job. In humid homes mould is the commoner problem, seen as white or grey powdery patches on the tape pack.

• Store tapes upright in their cases, wound fully to one end.
• Keep them away from magnets, loudspeakers and motors, and out of cars and sunny rooms.
• Play valuable tapes only on a clean, known-good deck; a faulty one can destroy a tape in seconds.

Floppy disks suffer magnetic decay, mould and damaged sleeves, and a mouldy disk can ruin the drive that reads it. Set the write-protect tab, store disks upright in closed boxes, and keep magnets away. Hard disks suffer mechanically, as lubricants stiffen and heads stick after long idleness. Flash memory in cards, phones and solid-state drives slowly loses its charge when unpowered for years, faster in heat. Old memory chips with a small glass window, erased by ultraviolet light, should keep a light-proof label over it.

Optical discs

Pressed CDs and DVDs store data in a thin reflective metal layer. On a CD that layer lies just under the label, so the label side is the fragile side. Poor sealing lets the layer corrode, called disc rot, seen as pinholes or bronzing. Recordable discs use organic dyes that fade with light and heat, and cheap blanks can fail within years. Store discs upright in proper cases away from sun and heat, hold them by the edge and centre hole, never stick labels on them, and write only on the clear central hub with a soft, solvent-free marker.

Data rot and migration

All of these media are temporary. The only durable preservation of data is copying it to current storage before the original fails, and keeping on copying.

• Image, do not just copy. A disk image is a complete, bit-for-bit copy of a disk, including the parts copy protection depends on. Enthusiast tools exist for cassettes, floppies, cartridges and memory cards.
• Checksums. Record a checksum, a short fingerprint calculated from a file, for each image; if a later copy gives a different checksum, it has been corrupted.
• Three, two, one. Keep three copies, on two different kinds of storage, with one away from home.
• Keep the originals too. An image preserves data; the original disk, tape and label are the collectable.

Copyright law generally lets the lawful owner keep a backup of software or recordings they own, but not share them, so check the position before distributing anything.

Manuals, boxes and paperwork

Most manuals and boxes were printed on cheap, acidic paper and card that yellow and grow brittle, and the glossy coated pages of many manuals stick together in humid heat. Staples rust and stain the paper around them. Silverfish and cockroaches eat paper and glue; termites eat card; rodents shred packaging for nests.

• Store manuals flat in individual polyester or polypropylene sleeves, or acid-free envelopes, in closed boxes.
• Keep paper apart from the device, in its own box, marked with the same inventory number. A leaking battery or perishing rubber foot can ruin a manual stored beside it.
• Keep boxes in their shape. Never flatten a collectable box. Fit clear polyester box protectors for valuable ones, and store boxes upright or lightly stacked so the bottom ones are not crushed.
• Inspect inserts. Expanded polystyrene is fairly stable, but decaying foam inserts should come out before they stain the box and device. Photograph and bag what remains, and note it in the record.
• Never repair with sticky tape. It yellows, its adhesive migrates into the card, and it cannot be removed cleanly. Tears and rusting staples are a paper conservator's work.
• Scan everything: manuals, boxes, warranty cards and receipts. The scans answer most questions without handling the originals, and they survive if the originals do not.

Warranty cards, dealer stamps and receipts are provenance, often worth as much as the manual. Sleeve them individually.

Stage 13Storage and Care: Conditions, the Indian Climate and the Routine

The mechanisms in Stages 11 and 12 all run faster in heat, humidity, light and dust, and slower in cool, dry, dark, still and stable conditions. Good storage does not stop decay; it slows it enough that your collection outlasts you. This stage turns that into numbers, materials, a home set-up that works in India, and a routine.

Target conditions

For a mixed collection, a practical aim is roughly 40–50% relative humidity and no more heat than a comfortable room. These are honest ranges, not precise laboratory figures, and stability matters more than the exact number. Air that swings from damp to dry every day, or from hot to air-conditioned cold, makes materials swell and shrink and invites condensation. A box that holds a steady 55% is better than a room that lurches between 35% and 75%.

Materials: use and avoid

The Indian climate

India is harder on gadgets than the temperate countries where most care advice is written, and the problems vary by region and season.

• The monsoon. For weeks, relative humidity across much of the country stays above 80%, indoors as well as out: the season of lens fungus, mould, sticky coatings and corroding contacts. Chennai and the south-east coast get their heaviest rain from October to December, so time the routine below to your own region.
• Coastal salt air. In Mumbai, Chennai, Kolkata and every coastal town, salt settles from humid air and speeds the corrosion of contacts, connectors, chrome and steel screws. Closed boxes matter most here.
• Northern heat. Summers in Delhi and across the plains regularly pass 40 °C, and top-floor rooms and parked cars get far hotter. Heat damages LCDs, swells lithium-ion packs and speeds every reaction in Stages 11 and 12.
• Dust storms. Pre-monsoon storms in the north drive fine dust into keyboards, mechanisms and lens barrels; closed cabinets keep most of it out.
• Dry northern winters raise static electricity, the handling hazard described below.
• Power cuts and voltage swings. Dehumidifiers and air conditioners stop with the power and humidity rebounds within hours, but boxes with silica gel keep working. Surges when power returns can damage equipment under test, so use a surge-protected strip or a voltage stabiliser.
• Termites and wet mopping. Termites eat card, paper and wood, and daily mopping splashes anything at floor level. Use steel shelving, a hand's width off walls and well off the floor.

Silica gel is the affordable backbone of Indian storage. Put it in lidded polypropylene boxes with the collection, allowing a few hundred grams for a medium box of about 20 litres, and more in the monsoon. Choose orange indicating gel, which changes colour as it saturates. Silica gel stops working once saturated, and in the monsoon that can happen within weeks, so check the colour regularly.

A hygrometer tells you whether any of this is working. Cheap digital thermo-hygrometers cost a few hundred rupees (2026) and are accurate only to within a few per cent, which is enough for watching trends. Check one with the salt test: seal it for eight to twelve hours in a small airtight container with a saucer of table salt dampened to a wet paste. It should read about 75%; note the difference and allow for it.

A dry cabinet, the electronic cabinet with a sealed glass door sold for camera equipment, holds humidity at a set level without refilling gel. A small one costs several thousand rupees and larger ones considerably more (2026). For a collection of cameras and lenses in a humid city, it is the single best investment after the cameras themselves.

Where in the home. Choose an interior room on a middle floor, not the top floor under the roof and not the ground floor in a flood-prone area. Keep away from outside and bathroom walls, kitchens, windows and direct sun. Put heavy items, including picture-tube televisions, on the lowest shelves.

Storage layout and display

Closed cabinets and lidded boxes beat open shelves for dust, light and humidity. Store cameras with the shutter released rather than cocked, and lenses capped at both ends. Keep tapes, discs and floppies upright, and never stack anything on a screen. A shelf of gadgets on display is a lovely thing, but daylight yellows plastics and fades labels. Display away from windows under LED lighting, which gives off almost no ultraviolet, rotate displayed pieces back into storage, and use glass-fronted cabinets to keep dust off.

Handling and static

Handle gadgets with clean, dry hands, and lift with both hands from underneath, never by knobs, handles, tone arms or a picture tube's neck. Cotton gloves reduce grip and make drops likelier; wear thin nitrile gloves where fingerprints matter, on lenses, polished metal and circuit boards. Never touch cartridge or board contacts, because skin oils corrode them.

Electrostatic discharge, the spark you feel from a door handle, can kill the chips on an exposed board without leaving a mark, most easily in dry weather and synthetic clothes. Touch grounded metal before handling an open board, wear an anti-static wrist strap inside a computer, and keep loose boards in anti-static bags.

Documentation

Keep one record per object, numbered to match its storage label: maker, model, variant and serial number; date codes; condition and working status, with the date last tested; what is present, from box to cables; source, date and price paid; every repair; storage location; and photograph references. Photograph every side, the label, the serial and any faults. Keep the catalogue as a plain spreadsheet that will still open in twenty years, backed up by the three-two-one rule from Stage 12, with a printed copy among your papers.

Disaster planning

Floods in Mumbai in 2005 and Chennai in 2015 showed how quickly ground floors and lower shelves are lost. Plan for water, fire and theft before they happen.

• Water. Nothing on the floor or under pipes and air-conditioner outlets. If electronics get wet, remove the batteries, do not switch on, and take them to a technician. Wet paper should be air-dried or frozen within about two days; a paper conservator can advise.
• Fire. Keep spare lithium-ion packs apart from the collection, ideally in a metal box, and never charge them unattended.
• Theft. Cameras and watches are small and easy to sell. Do not advertise your collection or address online.
• Insurance. Household policies may cap or exclude collections; a specified schedule needs your catalogue, photographs and receipts.
• A grab list. List the few irreplaceable pieces, and the drive holding the catalogue, to save first, and keep the list where your family can find it.

A routine

Stage 14Scarcity, Licences and the Valve Radio

For most of the twentieth century a gadget in an Indian home was a considered purchase, often a family's largest after jewellery. Import controls, high duties and licensing kept foreign goods scarce and expensive, and the devices that did arrive were kept, repaired and handed down. That scarcity shapes Indian gadget collecting today: fewer survivors of any one model, more repairs, and a great deal of family history attached to each set.

Radio arrives

Broadcasting in India began in the 1920s with amateur radio clubs, followed in 1927 by the Indian Broadcasting Company's stations in Bombay and Calcutta. The service passed to the government and became All India Radio in 1936, later also known by the name Akashvani.

Owning a receiver required a licence. Under the Indian Wireless Telegraphy Act, 1933, households bought broadcast receiver licences through the post office and renewed them each year, and the licence booklets, with their stamps and renewal entries, survive in many family papers. The requirement was eventually dropped. Booklets are now collected in their own right, and one found with a radio adds real provenance.

The valve radio years

After independence, import substitution meant that radios sold in India were increasingly made in India, often by local companies linked to foreign names. Philips, Murphy and Bush sets were made or assembled in the country, alongside Indian firms such as the Tata-linked Nelco. Murphy's advertisements featuring a baby's face are still widely remembered.

A typical set of the 1950s and 1960s was a wooden cabinet with a cloth-covered speaker, a glowing dial marked with the names of world cities, several shortwave bands, and often a green "magic eye" tuning indicator. Shortwave mattered: families listened to the BBC, Radio Ceylon and other distant stations as well as All India Radio.

The transistor

Transistor radios spread through the 1960s and 1970s and changed listening from a household event into a personal one. The portable became so common that "transistor" came to mean a radio. It went to fields, shops, cricket grounds and tea stalls. In some family-planning drives of the 1960s and 1970s, a transistor radio was among the incentives offered, an uncomfortable reminder of how much the object was worth to a poor household.

Collecting the licence era

Valve radios from Indian factories turn up regularly through scrap dealers, old repair shops and family clear-outs. Their enemies are termites in the cabinets, moisture in the paper capacitors, and rodents. Treat every one as unsafe to power until a technician has checked it (see Stage 8). Keep the dealer's label, any repair tags inside the cabinet, and the licence booklet together: they are the set's history.

Stage 15Doordarshan and the Colour Boom

Television came to India slowly, then all at once. An experimental service began in Delhi on 15 September 1959. Regular programming grew through the 1960s, and other cities followed in the 1970s. In 1975–76 the Satellite Instructional Television Experiment, using an American satellite, beamed educational programmes to community sets in some two thousand villages. On 1 April 1976 television was separated from All India Radio as Doordarshan.

The black-and-white household

For a middle-class family, a black-and-white set was a major purchase, and it was treated like furniture. Many Indian sets came in wooden cabinets with sliding shutters that closed over the screen, sometimes with a lock, and stood on legs or a stand under an embroidered cover. On the roof, an antenna was turned by hand towards the nearest transmitter, and a voltage stabiliser sat beside the set to protect it from fluctuating mains. Neighbours without a set gathered in homes that had one.

Colour, 1982

In 1982, the year Delhi hosted the Asian Games, Doordarshan began colour transmission, and national programming was carried by satellite. Demand for colour sets exploded. To meet it, the government eased rules on importing sets and kits for a period and licensed Indian manufacturers to assemble colour televisions. Through the decade transmitters multiplied across the country, and a television reached towns that had never had a signal.

Programmes drove sales. The soap opera Hum Log began in 1984 and Buniyaad in 1986. Cricket, and above all the 1987 World Cup co-hosted by India and Pakistan, sold sets by the thousand.

Stage 16The Suitcase Years: Cassettes, VCRs and Cameras

From the 1970s, some of the most desirable gadgets in India arrived in suitcases. Indians working in the Gulf states, many of them from Kerala, came home on leave with Japanese radio-cassette recorders, televisions and, later, video recorders, within customs baggage allowances and duties. Relatives in Britain, America and Singapore did the same. A gadget brought "from outside" carried status that no local brand could match.

The cassette revolution

The compact cassette made music cheap in India. Blank tapes were affordable, recorders were portable, and from the late 1970s Indian cassette labels, T-Series the best known, sold film songs, devotional music and regional music at prices far below records. Studies of the period, notably Peter Manuel's work on north India, show how cassettes created markets for music that the record companies had never served. Pirated and "version" recordings were everywhere.

The two-in-one, a radio and cassette recorder combined, became the household music centre. Sharp, Sony, National Panasonic, Aiwa and Sanyo were the prized names, and double-cassette models that could copy tapes were the most prized of all.

Video

Video cassette recorders arrived in the early 1980s, often through Gulf baggage or grey markets. Video libraries rented films on tape, video parlours showed them to paying audiences, and long-distance buses advertised video coaches. Weddings began to be filmed. Grey-market electronics had famous addresses: Delhi's underground Palika Bazaar and Chennai's Burma Bazaar were known in their day for imported goods of uncertain paperwork.

Cameras and film

Imported cameras were expensive, so for many families photography meant the studio: a formal portrait against a painted backdrop, taken on a large camera. Hindustan Photo Films, a public-sector company set up in Ooty in 1960, manufactured film and photographic paper, sold under the Indu name. Through the 1990s automated photo labs spread through Indian towns, and point-and-shoot film cameras became common wedding and holiday gifts before digital cameras replaced them.

Stage 17Indian Brands of the 1980s and 1990s

Behind high import walls, India built its own consumer electronics industry. Between the late 1970s and the late 1990s dozens of Indian brands made televisions, music systems and radios, some private, some owned by state governments, many working with Japanese or European partners. Most have vanished or survive only as licensed names. Their products are the most distinctively Indian gadgets there are, and among the least documented.

Who made what

State electronics corporations were set up by several state governments to build local industry. Keltron in Kerala, Uptron in Uttar Pradesh and Webel in West Bengal all made or sold consumer electronics, including televisions. The central public-sector ECIL in Hyderabad made televisions too, alongside its computers and defence work.

Private companies grew with the colour boom of 1982 and after. Onida, from Mirc Electronics in Bombay, became famous for advertising built around a horned devil. BPL grew from medical and measuring instruments in Kerala into one of the best-known television and appliance brands. Videocon, founded in Aurangabad, made televisions with Japanese technical partners and later a wide range of appliances. Salora, Weston, Dyanora and many smaller names competed for the same buyers, alongside long-established Philips India and Nelco.

Collaboration was the norm. A rear label often names a Japanese or European partner, and the same chassis could appear under more than one Indian badge.

After 1991

Economic liberalisation from 1991 lowered duties and opened the market. Japanese and Korean companies set up their own Indian operations, and by the late 1990s LG and Samsung were major forces. Many Indian brands of the 1980s declined, were sold or disappeared. Some old names were later licensed to other makers, so a modern product can carry a badge from the 1980s, a trap for anyone identifying by logo alone.

What to collect

• Early colour televisions with intact badges, rear labels and, ideally, invoices and warranty cards.
• Music systems and two-in-ones from Indian brands, which are rarer in good condition than the imported Japanese sets they competed with.
• Remote controls, brochures, price lists and dealer signboards. Paper survives badly in India and is often scarcer than the sets.
• Magazine advertisements. Bound volumes of Indian news and general-interest magazines of the 1980s are an excellent source for dating models and recording prices.
• Service manuals and circuit diagrams, often kept by retired repairers, which are now the only technical record of many models.

Stage 18Calculators, Computers and Consoles in India

India's computing story began in its research institutions long before computers reached homes, and for many Indian children of the 1990s the first computer they played on was a clone console plugged into the family television.

The institutional machines

The Indian Statistical Institute in Calcutta was among the first Indian institutions to acquire a computer, in the 1950s. At the Tata Institute of Fundamental Research in Bombay, a team designed and built TIFRAC, generally regarded as the first computer built in India, which came into use around 1960. In the mid-1960s the Indian Statistical Institute and Jadavpur University together built ISIJU, an early transistorised machine. Electronics Corporation of India Limited, set up in Hyderabad in 1967, went on to make computers of its own around 1970.

These machines, where they survive at all, belong in institutions. What collectors find are their traces: brochures, manuals, punched cards, printouts and photographs.

From IBM's exit to the PC

In 1978 IBM left India rather than reduce its ownership of its Indian business, as the law then required. The gap encouraged Indian companies. HCL, founded in 1976, was building microcomputers by the end of the decade, and Wipro, then best known for vegetable oil, moved into computers in the early 1980s. Policy changes in the mid-1980s eased imports of computers and components. By the 1990s assembled PCs from markets such as Delhi's Nehru Place and Mumbai's Lamington Road were filling offices and cyber cafés.

Two later devices are already collectable. The Simputer, a low-cost handheld computer developed in Bangalore and launched in the early 2000s, never sold in large numbers. The Aakash tablet of 2011 was a government-backed attempt at a very cheap tablet for students. Both are milestones of Indian design ambition.

The history of calculator assembly in India is poorly documented. For most families the calculator was an imported Casio or Citizen, and an Indian-branded example with its box is worth recording carefully.

Consoles and clones

Licensed video game consoles reached India late and expensively. What most children knew instead were unlicensed clones of Nintendo's Famicom, sold under many names in electronics markets, with cheap joypads, a plastic light gun and a multi-game cartridge promising hundreds of games that were mostly repeats. Handheld "brick game" players followed. Later, cyber cafés and gaming parlours introduced a generation to PC games.

Clones are collectable on their own terms. Boxed examples with Indian-market packaging are genuinely scarce, because nobody kept them.

Stage 19HMT, Titan and the Indian Wrist

For decades the Indian wristwatch was a hand-wound HMT, bought for a first job, given at a wedding, and worn for thirty years. Few Indian gadgets are remembered with more affection, and few are more complicated to collect honestly.

HMT

Hindustan Machine Tools was founded in Bangalore in 1953 as a public-sector maker of machine tools. It entered watchmaking in collaboration with the Japanese company Citizen, and its Bangalore factory began producing watches in 1961. HMT hand-wound mechanical watches became the Indian standard: sturdy, easily serviced by any local watch repairer, and priced within reach of salaried households.

Model names are part of the appeal: the Janata, the everyday watch, the Pilot, the Kohinoor, the Sona and many more, together with Braille watches for blind wearers. HMT later made automatic and quartz watches, but the hand-wound models are what collectors seek.

Competition from quartz and from Titan, and mounting losses, brought HMT's watchmaking to an end in the mid-2010s. News of the closure sent buyers searching for the last new stock, and the brand acquired a nostalgic following it had rarely enjoyed when it was everywhere.

Titan and the quartz decade

Titan, a joint venture between the Tata group and the Tamil Nadu government's development corporation, was set up in the mid-1980s and launched its watches in 1987 from a factory at Hosur. Its quartz watches, with designs that looked international, changed what an Indian watch could be. Early Titan models, with their boxes and papers, are now collected too. Other names with Indian followings include Allwyn, a Hyderabad public-sector firm better known for refrigerators, and Swiss brands long popular in India such as Favre-Leuba. For clocks, Morbi in Gujarat became the centre of Indian wall-clock manufacture, with Ajanta the best-known name.

The refurbished HMT problem

Because HMT watches were cheap and numerous, a large trade grew in refurbishing them: worn watches given newly printed dials, replacement hands and crowns, and polished cases, then sold as "vintage HMT". Many are honest, pleasant watches to wear. Very few are original, and they are often described as though they were.

Stage 20Telephones, Pagers and the First Mobile Years

In 1990 a telephone connection in an Indian city could take years to arrive. By 2010 India was one of the largest mobile phone markets in the world. Few countries have moved so far, so fast, and the objects of that journey are only now becoming collectable.

The landline years

Indian Telephone Industries, set up in Bangalore in 1948, made the black rotary-dial telephones that sat in Indian homes and offices for decades. Demand far outran supply. Waiting lists for a connection ran for years in many cities, and schemes that let applicants pay a large deposit to move up the queue were popular with those who could afford them. Long-distance trunk calls were booked through an operator, with an expensive "lightning" call for urgency.

Change came in the 1980s. The Centre for Development of Telematics, C-DOT, founded in 1984 with Sam Pitroda as its guiding figure, developed digital exchanges suited to Indian conditions. Mahanagar Telephone Nigam took over Delhi and Mumbai in 1986. Through the late 1980s and 1990s yellow-signed booths offering STD, ISD and PCO services, meaning long-distance, international and public calls, spread to every street corner and put the telephone within reach of people who would never have a line at home.

Pagers

Paging services arrived in Indian cities in the mid-1990s. A subscriber called an operator, who sent a short message to a belt-clipped pager, and the recipient then looked for a telephone to call back. For a few years pagers were a mark of the busy professional. Once mobile call rates fell in the early 2000s they disappeared almost completely, which makes working pagers with their boxes surprisingly scarce.

The first mobile years

India's first mobile phone call was made on 31 July 1995, when the Chief Minister of West Bengal, Jyoti Basu, in Calcutta, called the Union telecom minister, Sukh Ram, in Delhi. Early mobile service was expensive: calls cost several rupees a minute, and incoming calls were charged too. Handsets were costly and heavy.

Prices tumbled in the early 2000s. Incoming calls became free, prepaid recharge coupons made phones available without a contract, and cheap CDMA handsets from new operators brought millions onto networks. Nokia dominated the handset market, and its sturdy basic models, with dust-resistant keypads and, in some models, a built-in torch, became part of Indian daily life. Nokia manufactured phones near Chennai from 2006 until 2014. From around 2008 Indian brands such as Micromax, Karbonn and Lava sold large numbers of low-cost handsets, often with two SIM slots, before Chinese brands overtook them in the smartphone years.

Collecting phones safely and legally

Every handset carries an IMEI number, and tampering with it is an offence under Indian telecom law. The Department of Telecommunications runs a system for reporting lost and stolen phones, and a second-hand phone should be checked against it before purchase. Batteries in old phones are frequently swollen or dead; see Stage 11 before charging any of them.

Stage 21Collecting in India Today: Markets, Repairers and the Law

Indian gadget collecting is young, under-documented and full of opportunity. Many Indian-made objects have never been catalogued anywhere, and the repairers who understand them are retiring. A careful collector here is also, whether they intend it or not, a historian.

Where gadgets turn up

• Scrap dealers. The neighbourhood kabadiwala who buys old newspapers and metal also buys old radios, televisions and phones, and larger scrap yards accumulate them.
• Old markets. Mumbai's Chor Bazaar is the best known; Delhi's Lajpat Rai Market and Nehru Place, Bengaluru's SP Road, Chennai's Ritchie Street and Burma Bazaar, Kolkata's Chandni Chowk and Pune's Juna Bazaar all have dealers in old or second-hand electronics among the new.
• Repair shops. Long-established radio, television and watch repairers often hold unclaimed sets, spare parts and service manuals.
• Families and estates. House clearances after a death or a move are where boxed, documented gadgets appear.
• Online classifieds, auctions and collector groups, where prices are visible and comparable, and where a seller's history can be checked.

Prices vary more by city and seller than by condition. Watch completed sales for a few months before deciding what anything is worth, and treat early purchases as tuition.

Repairers and their knowledge

India kept gadgets working long after richer countries threw them away, and its repairers are a national resource. Many work from memory and hand-copied diagrams that exist nowhere else. When you find a good one, pay properly, return, and, with permission, record what they know: which models failed how, which parts substitute, which brands shared a chassis. That knowledge disappears with them.

The law in brief

Law changes, so check the current position before relying on this summary.

Why it matters

A Japanese Walkman is documented in a hundred books. An Indian two-in-one, an early Indian colour television, or an HMT with its guarantee card and the story of the first salary that paid for it, is documented almost nowhere. Keep the object, keep the paper, keep the story, and keep all three together.
