VHS (1976)

VHS Cassette

Launched late 1976 (Japan)

Launched in Japan forty years ago, the VHS video tape recorder standard helped to revolutionise they way we watch TV worldwide. But despite twenty years of popularity, VHS tapes are seldom seem today.

Developed by JVC, VHS found itself going head-to-head with Sony's Betamax in the early days (the so-called "Format War") plus a number of less well-known formats. VHS was cheaper and offered longer recording times, but Betamax had better picture quality and more compact cartddges. In the end VHS won and became de facto standard worldwide.

VHS had drawbacks though, often suffering from poor picture quality and the inconvenience of having to rewind the tape when you had finished.. and if you've ever rented a movie to find that the previous user hadn't bothered then you'll know how frustrating THAT was.

The relative ease-of-use and cheapness of VHS meant that it remained popular until the later 1990s (with product continuing well into the 2000s), despite several attempts to popularise something better. In the end it took two devices, the DVD player and the DVR to finally kill off VHS. Today, even those devices are being threated by video-on-demand services such as Netflix and Amazon Prime.

Collection of VHS movies

Even in the 1980s one of the main shortcomings of VHS was clear - the size of the tapes. The plastic case that movies came in typically measures 202 x 125 x 30mm or so which is essentially the size of a hardback book. Tape for home recording were a little smaller, but still bulky. Ten movies on VHS would require about a foot of shelf space to store, so if you enjoyed such things then you could soon run into problems with actually finding somewhere to put them. A single DVD package took up just half the space, and for things such as TV box sets you could easily put several episodes on one disk and squeeze two disks in one box without making it bigger. Modern BluRay packing is smaller still. Even then, DVD and BluRay storage can be a pain which is probably one of the reasons that digital distribution is growing in popularity.

But what do you do with old VHS tapes? You can't even give them away these days, and they are generally not accepted for recycling, instead they are destined for landfill. Companies such as Terracycle in the UK offer paid solutions to recycle VHS tapes but the process is not cheap. In fact the whole issue is a nightmare for the environmentally conscious, but there are some more.. errr. creative solutions out there.

Ford Fiesta Mark I (1976)

Available September 1976

Forty years ago little hatchback cars were still in their infancy. Still very much the era of the saloon car, the market had been shaken up by the introduction of the Fiat 127 in 1971 followed by the Renault 5 in 1972. These two very European cars started to steal market share from traditional automobile designs, and it soon became clear to car giant Ford that this was a type of product that could not be ignored.

First shipping in Europe in September 1976 after four years of development, the Ford Fiesta was the Blue Oval's answer to those funny little cars, heralding the point when the small hatchback evolved from something quirky and continental to something very mainstream.

Unlike almost all previous Ford Europe models, the Fiesta was front wheel drive and cleanly designed with all the practicality that a hatchback could offer. Most importantly, the badge on the front was an indicator of quality and reliability shared by its bigger siblings, the Escort and Cortina.

The Fiesta was a huge sales success, and of course every other car manufacturer followed suit. These little hatchbacks proved to be inexpensive to buy, cheap to run, relatively easy to drive and had a versatile load space that was handy if you wanted to move your 8-bit micro and portable TV or something. If you've ever tried to move something bulky in the back of a saloon such as BMW 3-series you will be all too aware of the limitations of a boot, even today.

It is perhaps worth noting that a contemporary phone system that you could have installed into your Fiesta would have cost far more than the car itself, and unless you wanted to lug lead acid batteries around then the car was the best option.

The Fiesta Mark I continued in production until 1983, replaced by the lightly revised Mark II which was sold until 1989. The same basic vehicle had an impressive production run of 13 years, and of course the Fiesta is still in production today with the Mark VI.

Back in 1976 a basic 950cc Fiesta cost £1856 in the UK. Today a car from the same era with the same specification will cost between £2000 to £4000, with the rarer and much more desirable sporty XR2 version typically selling for £8000 onwards.

Zilog Z80 (1976)

Launched July 1976

During the late 1970s and early 1980s the majority of home microcomputers ran on one of two processors: the MOS Technologies 6502 or the Zilog Z80 which was officially launched forty years ago this month.

A relatively sophisticated 8-bit processor, the Z80 found its way into a variety of computer systems such as the Sinclair ZX80 / ZX81 and Spectrum, Amstrad CPC and PCW range, Tandy/Radio Shack TRS-80 plus a variety of less-known systems. In business it found its way into a very wide variety of CP/M systems including the Osborne 1 and Kaypro II.

It also found itself into embedded systems, calculators, musical instruments and communications systems. In some ways the versatility of the Z80 predated today's ARM cores, with Z80s popping up all over the place.

What may surprise you is that even after 40 years of production, you can still buy new Z80s (part numbers Z84C0008PEG or Z84C0010PEG) for about €3.50, in the original 40-pin configuration. Not bad going for a simple 8-bit CPU.

Apple I (1976)

Apple I at the Computer History Museum, California

Launched July 1976

Forty years ago this month, Apple introduced their first product - the Apple I (also known as the Apple-1). Billed as a "fully assembled" system, in fact it was just a bare board to which the user had to add a power supply, case, keyboard, monitor and to be of any use a cassette interface was available too.

Based on the 6502 processor launched the previous year, the Apple I was a major step-up from the KIM-1 single board computer, although it was more than twice the price at $666.66 (around $2400 in today's prices). The KIM-1 was a primitive device compared to the Apple, which had 4KB of RAM as standard (expandable to 48KB), could output 40 x 24 characters on a composite video display, and when supplied with the cassette interface it could run BASIC.

Only around 200 units were ever produced, many of which were traded in for Apple II systems introduced in 1977. Maybe 60 or so Apple I machines still exist and examples can sell for hundreds of thousands of dollars. Each system was hand-built by Steve Wozniak in the garage of the parents of Steve Jobs.

The Apple I was on the market for a little over a year before it was replaced by the Apple II, the iconic 8-bit computer that sold around six million units. Technologically it wasn't much of a step up from the Apple I, but the II really was a fully assembled device that anyone could use rather than a hobbyist system. The Apple II continued in production for 15 years.

Although it sold in tiny numbers, the niche success certainly helped set up the Apple II and that is certainly a machine that transformed the early microcomputing scene. But if you want to see one.. go to a museum.

Lear Siegler ADM-3A (1976)

Lear Siegler ADM-3A

Announced July 1976

Once upon a time, there was a California company that produced a radically designed and rather beautiful device that transformed the way people dealt with technology. Over the years, this particular product gained a cult following that took on an almost religious fervour. You might be forgiven for thinking that this company was Apple, but it wasn’t. Instead this company was called Lear Siegler International (LSI), the year was 1976 and the product was the ADM-3A.

The ADM-3A was a dumb terminal, similar in concept to the DEC VT52 launched the previous year, and following on from the almost identical looking ADM-3 also from 1975. A simple device comprising pretty much of just a keyboard, screen and communications ports, it would plug into a contemporary computer which could range from a multi million dollar mainframe to a hobbyist microcomputer costing a few hundred dollars. The ADM-3A was much more usable than the ADM-3 though, supporting both upper and lowercase characters and having a cursor-addressable screen (like the VT52), both features the ADM-3 lacked.

Two things made the ADM-3A stand out. The first was the relatively low price of $1045.. which although equivalent to about a whopping $5500 today (much more than a top-of-the-range iMac) was actually a fair bit cheaper than the competition.

But perhaps the main thing that made it stand out was the design. Most terminals of the time were boxy affairs, but the ADM-3A curved instead. A clamshell design with a hinge in the back, the ADM-3A’s lines followed the shape of the CRT, swooping down to the base where the mainboard was installed. The curves were echoed almost everywhere, on the front, around the CRT and on the base. In fact, the only real appearance of straight lines was at the front where the keyboard was.

Lear Siegler could also produce the ADM-3A in different colours, which was a simple process of changing the plastics used in the moulding. But hang on... curves, different colours... doesn’t that sound a bit like the original Apple iMac G3? There are certainly some interesting parallels there.

The price of the ADM-3A steadily dropped, hitting just $595 in 1981 (equivalent to about $2000 today), shipping 150,000 by that point. Those were huge numbers of the time, and ADM-3As could be found hooked up to mainframes, Unix systems and even rudimentary home computers. Helping to introduce computing to the masses? That does sound a bit like another California corporation, doesn’t it?
 

Now, you might be wondering about the “Lear” name in the company. Lear Siegler was founded by the merger of two companies, one of which was Lear Avionics founded by William “Bill” Lear*. Lear later went on to build executive jets that still bear the “LearJet” name today, although he sold his interest in Lear Siegler in 1962. LSI still exists today, although simply called the Lear Corporation, and it employees 136,000 people… which is more than Apple does.

But there’s another parallel between Lear Siegler and Apple – the ADM-3A was launched at the same time as the original Apple I, Apple’s first commercial product. Coincidentally, the Zilog Z80 microprocessor was also announced in July 1976. All-in-all, it was a pretty good month for landmark technologies.

You can still buy a used ADM-3A today, although most of the available ones seem to be in the US with prices at typically $400 to $500. And in case you don’t know what you would do with one, one particular mad genius interfaced one with a Raspberry Pi. Oh yes... as for cult there was a Usenet newsgroup called alt.religion.adm3a in the 80s and 90s, presumably created for followers of the One True Terminal.

* Lear invented the first car radio for Motorola, created the 8-track tape and pioneered business jets plus a whole lot of other stuff. He was a very clever guy. Eventually the LearJet corporation ended up as part of the giant Bombardier group, but the Lear name still lives on in the Lear Corporation which has a history of the company here.

IBM 3800 Laser Printer (1976)

IBM 3800 Printing Subsystem

Announced April 1976

Announced forty years ago this month, the IBM 3800 was the world's first commercially available laser printer. In one form or another the 3800 was in production for a decade-and-a-half and revolutionised high-volume computerised printing.

Beating rivals Xerox to market by a year, the IBM 3800 was a massive device that could typically print about 167 pages per minute. Today, even a high-end device such as the Ricoh Pro 1357 would struggle to keep up. Crucially though, the IBM 3800 used continuous stationery rather than cut-sheet paper which must have helped with the throughput. The print resolution was about 160 dpi.

It wasn't cheap - even the 1987 model cost a staggering $175,000, but then you would hook it up to an IBM mainframe which would have cost you a couple of million dollars. Strictly an enterprise computing component, the 3800 must have been a welcome relief from the deafening noise of banks of impact printers.

It wasn't until the mid 1980s that laser printing because remotely affordable on the desktop, with the breakthrough product being the original HP LaserJet. IBM span off the printing business as Lexmark in 1991, which still exists today.

Today you can pick up a new small laser printer for less than €50, with typical very high volume systems coming in at €35,000 or more.

MOS Technologies KIM-1 (1976)

Launched April 1976

These days, single-board computers such as the Raspberry Pi and Arduino are all the rage. These small and inexpensive devices are ideal for hobbyist and industrial application, but of course this is not a new idea. Forty years ago one of the most important single-board computers was launched: the MOS Technologies KIM-1.

MOS Technologies had produced low-cost 6502 processor the previous year, but (as today) the problem was getting it into the hands of people who could actually DO something with it. So, the KIM-1 was produced as a basic bare-boned system that people could adapt, at the relatively affordable price of $295 (equivalent to around $1050 today).

It was a primitive device. The 8-bit 6502 CPU came with 1K of RAM, a small LED display, and a hexadecimal keypad. It had a couple of expansion ports and pair of serial interfaces, which meant that it could be paired with a teletype for output or a cassette recorder. Later independently-produced expansion modules included a video board.

The design was adapted and expanded by other manufacturers too, and the KIM-1 and its derivatives became a significant success and helped to establish the 6502 as one of the key processors of the late 1970s and early 1980s. In the end, MOS Technologies ended up being bought up by Commodore, and the ideas behind the KIM-1 were expanded and eventually developed into the Commodore PET.

In Europe, the KIM-1 is a very rare device indeed. They are occasionally available in the US with prices ranging between $300 to $1000, with a typical price of around $700. Of course, in order to get it the best out of it you would need a whole pile of obsolete equipment to go with it, or alternatively you can bamboozle yourself with this Javascript KIM-1 emulator.
