2017: things that didn't quite make the cut

This year we've covered gadgets and geeky things from 1907, 1927, 1967, 1977, 1987, 1997, 2007 and 2012 (and actually even 2017). Out of all these years, 1977 stands out as the year that gave us the Commodore PET, Apple II, TRS-80 Model I, Atari VCS and DEC VAX. All of these were ground-breaking technologies that helped to shape the world we live in today.

But there were a few other things that didn't quite make the cut which are worth making a note of.

1927 may have been the year of the Jaffa Cake, but it was also the year that Newcastle Brown Ale was launched. Unusually for a brown beer, it comes in a clear bottle and the recipe has only slightly changed over the past 90 years to remove the caramel colouring. A huge export success, Newcastle Brown has been a little taste of home for Geordies the world over.

As well as chunky telephones and fancy cars, 1967 also brought the world's first Automated Telling Machine (ATM) in Enfield, London. Despite the rise of cashless payments, ATMs are still very common fifty years later... and perhaps just a little bit too common.

Another computer system launched in 1977 was the NASCOM-1 which was a computer kit built around a single board. Popular in its day due to the relatively low cost, it couldn't really compete with the fully assembled systems from rivals.

 1977 also saw the release of the classic Crowther and Woods Colossal Cave Adventure. Featuring a rudimentary natural-language processor and some fiendish plot twists, Colossal Cave ended up being ported to a huge variety of computer systems and was massively popular.

We talked about the 1977 Matra Rancho, a stylish affair that looked like it could go anywhere but couldn't. Launched the same year, the Lada Niva actually could go just about anywhere but the 1970s Soviet styling couldn't compete with the chic French Matra. Thanks in part to its lightweight unibody design and dependabili, the Niva survives to this day (called the Lada 4X4 in most markets) where its simple and rugged charms start at less than €11,000 for a new one.

In 1987, personal computers were becoming more powerful with the likes of the IBM PS/2, Apple Macintosh II and Acorn Archimedes but they were also becoming more portable. The Compaq Portable III replaced the small CRT of previous models with a 10" plasma screen. At 9 kilograms it was still no lightweight, but it was finally a practical and reliable business computer that could be used on the move.

That's the lot for this year. See you in 2018.

Matra Rancho (1977)

Matra Rancho
Launched 1977

The Matra Rancho. If you’ve never seen one before, just one look will tell you that this is a tough offroad vehicle that can go absolutely anywhere. And that one look would lead you to absolutely the wrong conclusions.

Despite its rugged looks, the Rancho was basically just a two wheel drive pickup truck with a fibreglass body on the back. With no more off-road capabilities than any other standard late 1970s car, the Rancho promised something that it didn’t deliver. But what it did eventually deliver was no less important.

A brief history lesson – Matra was an industrial combine with a profitable line in armaments that almost accidentally became a car manufacturer by taking over sports car builder Automobiles René Bonnet. Matra’s main interest may well have been the use of fibreglass in the company’s Djet two-seaters, but this blossomed into motorsport (winning both the Formula One Drivers’ and Constructor’s championship in 1969), the 24 Hours of Le Mans in 1972, 1973 and 1974 plus a host of other racing trophies. The road car division continued to make sports cars including the novel Matra Bagheera and Murena which featured a single row of three seats.

Matra ended up in partnership with the Chrysler-owned Simca company to sell the Bagheera and Murena. Matras expertise in prototyping and fibreglass led to a new project that was quite a radical departure – the Matra Rancho. The Rancho was designed by Matra’s chief designer Antonis Volanis, as were the Bagheera and Murena.

The inspiration for the Rancho was the Range Rover, launched in 1970. Even then the Range Rover was an expensive and thirsty beast, and Matra thought that they could deliver a lot of the same things (looks and lots of space) for a lot less money. The compact Simca 1100 hatchback was the basis for this, although strictly speaking Matra standard with a pickup variant.

Onto the back of the chassis, Matra attached a large cab made primarily from fibreglass with lots of glass. It had a split tailgate (like the Range Rover) and lots of black plastic to make it look rugged. In optional seven seat form the Rancho was arguably the first MPV, and this hybrid of normal car and off-roader could be argued to be the first Crossover too.

The 80 horsepower engine didn’t have anything like the punch of the Range Rover’s 130 HP v8, but where the Range Rover weighed over two tons the Rancho came in at just 1130 kilos. With an array of spotlights on the front, an integrated roof rack above the driver’s seat and a practical interior which was quite nice by 1970s standards, the Rancho did have a lot going for it.

It had its flaws. The two-wheel drive system was exactly the same as you’d find on a normal Simca 1100 hatchback, and ground clearance was a lot more limited than it looked. But perhaps the worst problem was rust – pretty much everything rusted except for the fibreglass (a problem that also drove the Bagheera to near extinction).

Over 56,000 Ranchos were built, first as the Matra-Simca Rancho and then the Talbot Matra Rancho when Chrysler sold its European operations to PSA (Peugeot Citroën). Although thousands were exported to the UK, as of 2017 there are only three left on the road. You would be hard pressed to find one for sale anywhere in the world, but they do occasionally come up for a few thousand euros each.

Many of the ideas of the Rancho were incorporated into Matra’s next production car – the Espace. Although the Espace was originally designed for PSA, it ended up as a Renault and because the world’s first purpose-built MPV (unlike the van-derived Rancho). The Espace was a huge success for Matra, but eventually Renault took the production in house. This move stripped Matra of a successful product, and with a final swansong of the Avantime they ceased car production in 2003.

These days compact crossovers with rugged looks, lots of space but limited off-road capabilities are very common, but you are more likely to see the Matra name on one of the electric bikes they currently manufacture... or perhaps the wrong end of a guided missile. Like many automotive innovators, Matra missed out on the market it helped to create.

Digital VAX-11/780 (1977)

VAX 11/780
Launched October 1977

1977 was a significant year for technology, with the launch of several different brands of microcomputer, games consoles, laser printers and even smart watches. Some new launches seemed less ground-breaking but were perhaps just as important, and the Digital VAX was one such product.

Digital Equipment Corporation (usually shorted to “Digital” or “DEC”) had been a disruptive pioneer in the “small” minicomputer market from the 1950s onwards, best known for their PDP range including the popular 16-bit PDP-11 which was instrumental in the development of Unix.

Time marches on, and by the late 1970s the PDP range was looking tired. So, in October 1977 DEC launched the first of their VAX range, the VAX-11/780. Somewhat backward compatible with the PDP-11, the VAX introduced a 32-bit architecture and virtual memory addressing.

The VAX was designed to be easy to program, and along with it was launched the new VAX-11/VMS operating system which was thoroughly up-to-date in a 1970s sort of way. DEC also had its own version of Unix called ULTRIX and eventually BSD Unix became available too. This made the VAX-11 range the computer of choice for many corporations and universities.

The “minicomputer” name given to this type of machine is unfamiliar today, and given the huge bulk of the VAX-11/780 it seems ridiculous. However, the VAX was “mini” compared to the vast mainframes that IBM offered, and all you would need for an 11/780 was a suitably air-conditioned room with a three-phase power supply rather than a dedicated building. Later VAX-11 models could run off a standard plug. Having that much power and flexibility in a relatively compact computer added to the appeal.

Crucially, these were multi-user computer systems. Dozens or even hundreds of people could connect to a single VAX, and those VAXes could be networked together. Files could be shared securely and applications could be run, typically using a dumb terminal such as a VT52.

The preferred operating system for VAXes was VMS, and this too was a significant step forward. An extremely stable OS, VMS became the choice of businesses that didn’t want downtime. Because DEC controlled both the hardware and software, it made it much easier to make sure everything worked together. Potentially you could run a VAX/VMS system for years without downtime unless you wanted to upgrade the OS or run a standalone backup.

VMS became a significant inspiration for Microsoft’s Windows NT platform, used by every modern version of Windows. This is no coincidence, as Dave Cutler was a technical lead on both OSes (later moving to help develop Microsoft’s Azure platform). In the smaller systems market, NT is the only effective opposition to Unix-derived systems such as Linux, Android and iOS.

The VAX line was very popular, and over the years the range expanded to include small MicroVAX systems all the way up to supercomputers. Hugely popular at first, the VAX suffered as the minicomputer market decline in the face of business PCs, which eventually led to DEC being taken over by Compaq, who in run were taken over by HP. Although the last VAX computer was built in 2005, the operating system (now called OpenVMS) was ported to DEC’s Alpha platform, then Intel Itanium with a port to x86 in the works. HP still promote OpenVMS for running mission critical applications.

The VAX-11/780 is hardly a collectable item today due to its sheer size, and most second-hand bits of VAX hardware are probably bought by people keeping ancient installations running. But you don’t have to look far to see the influence of VMS – the architecture of any modern Windows PC is certainly a nod in that direction.

Research Machines 380Z (1977)

Research Machines 380Z
Launched October 1977

1977 was the dawn of the microcomputer revolution, with the stateside launch of the Commodore PET, Apple II and TRS-80 plus the 8-bit Atari VCS games console. But the US didn’t have it all to themselves, and in October 1977 the UK saw the launch of the Research Machines 380Z (or RM or RML 380Z for short).

Aimed primarily at the education market rather than home or business users, the 380Z was a massive beast even for 1977. Built like a tank, the enormous metal case was designed to be rack-mountable, but the external keyboard was also a big metallic lump too.

The name itself should give a clue that the 380Z was based around the Z80 CPU. The enormous case it came in reflected the wealth of expansion options beyond that – floppy disks, hard disks, video cards, interface cards and memory modules could be slotted in, make the 380Z a hugely powerful computer. In fact, the 380Z didn’t even have a motherboard as all components were on a card, which made it easy to modify or repair.

Although originally housed in a light blue case, the 380Z quickly evolved into the imposing black case that became very common in schools. Even when rivals such as the BBC or ZX Spectrum started to appear, the 380Z remained a serious computer for serious work – one that could do things that other (and it has to be said – cheaper) computers could not. The 380Z could run the business-standard CP/M operating system, but it wasn’t really marketed as a business computer. Just to prove its scientific and educational leanings, the computer was actually stylised as the 380Ƶ with a stroke on the "Z" to make it looks less like a "2".

Fully-loaded, the 380Z would cost over £3200 (almost the price of two basic Ford Fiestas) with the very basic models coming in at just under £1000 (about half the price of the aforementioned Fiesta). It was certainly an expensive system, but Research Machines also eventually created the diskless LINK 480Z which could use the 380Z as a file server, which was extremely advanced for the time.

Having found a profitable niche, RM went on to produce the Nimbus range of somewhat-PC compatibles, and after that it concentrated on PCs sold to the education market. RM finally dropped out of the hardware business in 2014 but it still exists today as a service provider to education.

These days 380Zs are a rare find on the second hand market, if you can find one they seem to be a few hundred pounds each. Due to the robust nature of their construction, there’s a very good chance that it will still work though.

Pot Noodle (1977)

Pot Noodles in the wild, 2017
Introduced 1977

A familiar snack food for students and bedsit dwellers, the Pot Noodle range was launched in the UK in 1977 and quickly became a popular and somewhat notorious product.

Instant noodles were invented in Japan in the 1950s with the Nissin Chikin Ramen. The same company then imported instant noodles in a cup in the the US in the early 1970s. This phenomenon had been spotted by Golden Wonder, who then introduced a version of it into the UK in 1977.

Preparation is simple enough. Boil a kettle, pour it in, wait a few minutes and stir. Sometimes there is a sauce packet to add. There's a tendency for the noodles to be high in fat and salt, and of course you shouldn't eat them all the time… nonetheless, the Pot Noodle did really open up new culinary adventures if all you had was a kettle.

Advertisements over the years ranged from the tame to the highly controversial, but they helped to make the Pot Noodle a rather laddish cult product. Although Golden Wonder sold the brand off years ago, they are still available today and retail for around £1 per pot. Although vintage Pot Noodles aren't really a thing, there's a lively trade in collectable spinning forks and matching mugs to go with your secret noodle obsession if you so desire.

Atari VCS / 2600 (1977)

Launched September 1977

1977 was the dawn of home computing, with the Apple II, Commodore PET and TRS-80 Model I all being launched within months of each other. But another early computing pioneer also found success in the same year, and that was Atari.

Launched in September 1977, the Atari Video Computer System (“VCS”) was an early second generation console that came after the 1970s wave of single purpose games machines that could typically play Pong and nothing else. Based around a cut-down version of the 6502 CPU called the 6507, the Atari VCS was designed from the start to be a highly flexible system that could play a wide variety of games.

Atari VCS "Heavy Sixer" (1977)

One key thing that made the VCS easy to use was the cartridge system. Instead of struggling to load a game from tape or splashing out on a very expensive floppy disk drive, the VCS loaded in games from cartridges instead. Although it wasn’t the first cartridge console on the market, the VCS was the first one to be a real success.

Games included the ubiquitous Pong, Space Invaders, Breakout, Pitfall, Centipede, Defender and later on a poorly received version of Pac-Man and the infamous E.T. Despite the VCS’s fairly crude colour graphics and sound and the relatively high price of the cartridges themselves, the VCS and many of its games went on to sell in huge numbers.

Atari 2600 ad (1982)
Priced at just $199 at launch, including a game and two joysticks, the VCS represented impressive value for money. Cartridges were relatively expensive, typically coming in at $20 or more. However the cartridges were easy to use… and crucially for Atari, almost impossible to pirate.

The original VCS models were made in Sunnyvale, California and are known as “heavy sixers” because they have six switches on the top and a more solid construction than the later “light sixers” built in Hong Kong. Further revisions followed, with the fake wood panel surviving until 1982, but the VCS name was changed to 2600 in 1980. In one form or another, the VCS / 2600 remained in production until 1992, giving the console a staggering 15 year run with almost unchanged hardware, selling 30 million units in the US alone.

Despite ending production, the VCS / 2600 remained popular, and in 2004 a modern interpretation was made called the Atari Flashback which is currently in its eighth generation. A top-of-the-range Flashback with an HDMI connector and a huge number of games costs around €170, an original 2600 console can cost from next to nothing up to several hundred euro depending on exact model, condition and bundled games with consoles quite commonly available.

In 1983 a crash in the video games market led to Atari being sold by its then parent company, Warner Communications, and it split into two. On part of it was bought by Jack Tramiel (who founded rivals Commodore) and which later went on to make home computers including the Atari ST. The company’s name and assets have changed hands many times over the years, but “Atari” still exists as a gaming brand today.

TRS-80 Model I (1977)

TRS-80 Model I
Launched August 1977

1977 saw three key products launched that helped to bring microcomputers into homes and businesses. These were the Commodore PET, Apple II and the TRS-80 which was launched in August 1977.

The TRS-80 (later called the TRS-80 Model I) was sold worldwide through Tandy and Radio Shack stores, and used a Zilog Z80 processor - this gave the computer its "TRS-80" moniker. Designed relatively quickly, the TRS-80 was both versatile and troublesome which gave rise to a nickname of "Trash-80". Despite the problems, the TRS-80 was a significant commercial success and several other products were released under the "TRS-80" name over the years.

Back in 1977, Radio Shack owned over 3000 stores in the US with hundreds more worldwide either using the "Radio Shack" name or the "Tandy" name of its parent company. Inspired by the success of the Altair 8800 launched in 1974 and with a desire to sell higher-ticket items, Radio Shack engineers quickly designed an expandable fully-assembled computer with prices at launch as low as $500 (compared to $1300 for the Apple II).

TRS-80 with Expansion Interface
The original TRS-80 had its problems. Firstly, the ability to display lowercase characters was deleted in order to save a few dollars of the price, the supplied monitors were of questionable quality, the keyboards suffered from keybounce (where multiple characters get entered for one keypress), the cassette tape interface was unreliable, the floppy disk system was full of bugs, connectors ended up suffering from corrosion and the expansion interface would tend to make the whole computer reboot. The implementation of BASIC was also pretty crude and the operating system was somewhat primitive. The graphics were also crude, there was no support for colour and there was no sound.

Despite these the TRS-80 had the advantage that you could not only rock up to a Radio Shack store and buy one, but if it went wrong you could take it back to the same store and they would fix it. This was a huge advantage over Apple and Commodore who had to build up a distribution network through partners. The design was steadily improved and problems fixed by Tandy themselves, and a range of aftermarket accessories and replacements became available to fix some of the design defects.

Peripherals continued to become available, including hard disks and printers and joysticks and third party suppliers made a wide range of software available for the TRS-80 (even if Tandy didn't publicise the fact very well). Various operating systems were available too, some through Tandy and several more through third parties, giving the TRS-80 an appeal to tinkerers are well as the home and small business users it was aimed at.

TRS-80 Model III
The first major revision of the TRS-80 came in 1980 with the Model III (the Model II was something different) which moved everything into one box with better hardware and software overall. In 1983 the Model 4 was launched with further enhancements and the ability to run CP/M. There was also a transportable version launched the same year, the TRS-80 4P, and the final model released was the 4D in 1985 – this model remained available until 1991.

The Model I and its successors sold well in North America and Germany, but not so well in other markets such as the UK. Although the TRS-80 name found its way onto many other computers of varying success, these were all largely incompatible as they had very different architectures. Over the next few years Tandy’s microcomputer business continued to grow and they manufactured a variety of systems for other companies as well as their own. However, in 1993 Tandy quit making computers and sold its assets to AST.

Tandy and Radio Shack continued going, but a slow decline had set in. In 2015 Tandy/Radio Shack declared bankruptcy, followed by a buyout and another bankruptcy in 2017. At present a few stores are left trading, but the once great Tandy/Radio Shack empire is just a faint echo of what it once was.

These days if you are after any model of TRS-80 will will probably have to import one from the US (remember in Europe you'll need a transformer else you will blow the power supply). Prices go up to about $500 or so depending on model and specifications.

Apple II (1977)

Apple II (1977)
Released June 1977

Think of great Apple products. There’s the iPod, iPad and the iPhone which were all launched between 2001 and 2010, the original Apple Mac which was launched in 1984... and before that was the Apple II, launched in 1977.

Like all those other devices, the Apple II really represented a paradigm shift. It was one of the very first professionally designed, pre-built and fully-features microcomputers that just anybody with enough money could go out to buy.

Just one year previously, Apple had launched the Apple I. Technologically similar to the Apple II, Apple’s original computer didn’t even come with basic things such as a keyboard or case. The Apple II took those underpinnings, including the 6502 CPU, and created a computer “appliance” rather than a hobbyist kit.

As with the Apple I, Steve Wozniak designed the internals which Steve Jobs took on marketing and responsibility for industrial design. Jobs gave the task of designing the look of the Apple II to Jerry Manock, a fairly unsung hero of Apple design who was responsible for many of their early products.

Manock’s design of the system and many of its peripherals gave the Apple II a coherent and professional look. But inside, Wozniak had used several clever tricks to develop a machine that outclassed its early 8-bit opposition in many ways, in particular with rudimentary colour and sound. Added to that, the Apple II had impressive expansion capabilities including a variety of add-on cards that could eventually give SCSI, parallel and serial interfaces, and there were games paddles, disk drives and more. Peculiarly the Apple II was hindered by only being able to display uppercase characters.

VisiCalc (1979)
The introductory price in the US was just shy of $1300, which over $5000 in today’s prices. That seems like a lot, but you can easily spend that much money on a high-end Mac even today. The Apple II was a huge success, even at those prices, and in one form or another it continued on sale until 1993. It also helped to create the microcomputer software industry, including VisiCalc – the first electronic spreadsheet for personal computers.

The Apple II went through several fairly minor revisions during its 16 year lifespan. One reason for this unusual longevity was the II’s success in schools in the United States, where a wide range of software took advantage of the II’s colour capabilities.

For collectors, there are usually quite a range of Apple IIs available second-hand. Prices range from few hundred dollars for a basic system up to several thousand for rarer versions, including the original “Revision 0” units. Alternatively, software emulators are available for most platforms and are much cheaper.

Along with the Commodore PET and the Tandy/Radio Shack TRS-80, the Apple II helped to introduce many households and businesses to computing and in doing so they changed the world forever.

Hewlett-Packard HP-01 (1977)

HP HP-01
Launched 1977

Wearable technology is nothing new. Forty years ago we saw the first digital watches, but even then some companies thought that the little computer on your wrist could do so much more. One such company was Hewlett-Packard, who decided to combine the functions of one of their famous line of calculators with a digital watch to come up with something quite unique.

The HP-01 was what Hewlett-Packard called a "wrist instrument". Along the top were nine seven-segment LED displays, underneath were 28 keys. Four keys were raised (Date, Alarm, Memory and Time) so they could be pressed with a finger, two semi-recessed keys (Read/Recall/Reset and Stopwatch) plus 22 recessed keys that you pressed with the supplied stylus which was either a mini one hidden in the wristband or the end of a specially-designed pen.

Inside were three batteries, two to power the display and one to power the tiny logic board. These batteries could be changed by a jeweller, or HP sold a special kit so that the user could change them. The watch itself was either housed in a steel or gold casing.

It was much more than a digital watch with a calculator added on, because the HP-01 treated the time and date as just another data type. Rather like a modern spreadsheet application, you can take the time and perform mathematical functions on it.. but the HP-01 does it in real time. As an example, if you are making an expensive long-distance phone call then the HP-01 can be programmed to tell you how much it is costing in real time. The HP-01 was also cleverly future-proofed with a "21" button allowing dates to be programmed for the 21st century.

HP-01 ad, 1978. Click to enlarge.
The HP-01 was certainly clever, but it was also a product desperately seeking a market. One pitch was aimed at lawyers:
Truly, with HP-01, you have a professional instrument capable of meeting a broad spectrum of your professional needs. It can handle everthing from remembering dates on the court calendar to calculating your time costs.

It can remind you of an important call up to four days in the future. And then tell you the number to call.

It can compute how much interest your money will earn or convert the time spent with clients into accurate calculations of fees.

In short, the professional applications are virtually unlimited.
With prices starting at $650 for the base model (more than $2500 today) the HP-01 was quite expensive. It was also bulky and rather tricky to use and despite its unique qualities, it was not a success. HP did experiment with an upgraded version, but in 1979 they threw in the towel and production of the HP-01 ceased. The HP-01 was Hewlett-Packard's first and last digital watch.

Today the HP-01 is a fairly rare device, with prices starting just shy of €1000 for one in a reasonable condition up to several thousand euro for really good models. Of course, any type of contemporary smartwatch is several orders of magnitude more powerful... but even those devices are still solutions looking for a problem.

Xerox 9700 (1977)

Launched 1977

Forty years ago we were seeing the start of a boom in personal computing.. but at the other end of the scale we were also seeing the dawn of digital imaging, in this case with laser printers.

The Xerox 9700 was launched in 1977, and although it lagged behind the IBM 3800, the Xerox was much closer to today's office laser printers than the IBM which was basically a very fast line printer. Capable of a maximum throughput of 120 pages per minute on cut sheet paper at up to 300 dpi, the Xerox 9700 could combine text and graphics in ways that hadn't previously been possible.

It was a big beast, which was understandable when you realise that it was basically three things joined together. Xerox took the guts of one of their own photocopiers and added a unit containing the laser and imaging system to it. Then they bolted a DEC PDP 11/34 to the whole thing to act as a controller. Sharp eyed readers may notice that in the picture the PDP 11 is being controlled by a Lear-Siegler ADM-3A.


Xerox 9700
It was huge and hardly cheap. Even in 1980 after it had been around for a while, the Xerox 9700 still started at $35,240 (worth about $100,000 today). It took about another decade for laser printers to hit the mass market with devices such as the Apple LaserWriter or HP LaserJet range.
Forty years later, Xerox still make printers including huge devices such as the Xerox Nuvera range which cost almost as much the 9700 did back in the day.

Commodore PET (1977)

Early model Commodore PET
Announced January 1977

Throughout the mid-1970s there were the seeds of a revolution were being sown. After 1975 hobbyist microcomputers such as the Altair 8800 were being offered to the public. After that, relatively low-cost microprocessors such as the Zilog Z80 and the MOS Technology 6502 had been developed into basic systems and board such as the Apple I and KIM-1, but these still were still strictly for hobbyists and engineers.

But 1977 saw the first systems that businesses or consumers could buy and use out-of-the-box. Professionally designed and fully functional, these early commercial offerings sparked the revolution that had been brewing for a few years. This year saw the launch of three highly significant systems in the US - the Commodore PET, Apple II and Tandy TRS-80.

The Commodore PET was announced at CES in January 1977, although the first units didn't ship until October and production levels didn't really meet until early 1978. In terms of announcement date, the PET beat its Tandy and Apple rivals, but those those systems actually shipped to consumers earlier.

The name PET stood for "Personal Electronic Transactor", and it was strikingly designed in an all-metal case with an integrated chiclet keyboard and data cassette recorder. Perched on top was a trapezoid-shaped 9" CRT display, giving the whole thing a look reminiscent of a Mesoamerican pyramid.

Commodore was no startup company - founded in 1954 it had started with typewriters before moving into adding machines and electronic calculators. Founded by industry legend Jack Tramiel, Commodore had bought Chuck Peddle's MOS Technology to secure supplies of the 6502 processor for use in calculator products. Peddle convinced Tramiel that a microcomputer was the way forward, and since Commodore was being hit by a slump in fortunes after a collapse in the calculator market, the company changed direction.

Early PETs featured a 1 MHz 6502 CPU, with RAM options ranging from 4KB to 32KB. Storage was a built in data cassette ("datasette") next to the keyboard, which did mean that on early versions the keyboard was a cramped affair. Over time a wide range of upgrades became available, including floppy and hard disks, printers, plotters and the PET's IEEE-488 interface could talk to a variety of scientific and engineering equipment too.

Later model Commodore PETs
Over the five years of production there were various upgraded models, with better keyboards, bigger screens, more RAM and better graphics. Along the way the cute "PET" name was dropped and the machines took on the name "CBM" (for Commodore Business Machines), but it didn't stop people calling them "PETs".

The PET sold very strongly into schools and colleges, thanks to its sturdy construction and reliability. However, the poor graphics capabilities meant that it didn't sell well in the booming home market, so Commodore followed up the PET with the successful VIC-20 in 1980 and the legendary Commodore 64 in 1982, both based on the 6502 processor. The 64 sold in millions and is the biggest selling computer model of all time.

Prices today for these machines varies from next-to-nothing up to €1000 or so, depending on model and condition. Although the PETs themselves were highly reliable, disk drives were always less common and more fragile and can be hard to find today. Alternatively, if you fancy a virtual PET rather than a physical one the VICE emulator emulates pretty much all 8-bit Commodore machines and runs on a wide variety of platforms, including Windows, Mac and even Android smartphones.
