2022 – things that didn’t quite make the cut

We covered quite a bit of retro tech this year, but there are a few things we didn’t talk about that are still worth a mention.

Let’s start with the automotive world. One of the more unusual vehicles to ever be produced in quantity is the DUKW (colloquially called the “Duck”), a six-wheel drive amphibious vehicle designed during World War II and manufactured by General Motors from 1942 to 1945. Excelling in amphibious attacks and traversing beaches, the DUKW could carry supplies or troops in a wide variety of environments. 21,000 of these machines were built, and some are still in use as tourist attractions today.

Where the DUKW was a bit of a barge, the Volkswagen Phaeton – introduced in 2002 – was a different type of barge. A large luxury car, sharing some of its DNA with Bentleys, the Phaeton was a rare entry into the luxury car market for the Volkswagen marque. Elegant and very understated, the Phaeton was a very discrete vehicle which gained some fans, but most luxury buyers were not interested and it wasn’t a sales success even though production continued until 2016. Today, the Phaeton is an extremely inexpensive buy for what it is, but it can be prone to enormous garage bills if it goes wrong.

From real-world cars to a fictional one – the Knight Industries Two Thousand (or “KITT” for short) was one of the stars of the 1982 TV Show “Knight Rider”. Based on a Pontiac Trans Am, KITT featured its own AI system which was capable of self-driving, speech recognition and synthesis, in-car communications (all of which are available today) and… errr… well a load of stuff that frankly isn’t. 23 KITT cars were made for filming, but most of these were destroyed. A handful of originals survive, but you are most likely to come across a replica.

Computers and cars came together in a different way with the 1982 Namco game, Pole Position. One of the first 16-bit arcade games, Pole Position offered unrivalled gameplay for a racing game, usually coming in a sit-down version with a proper steering wheel, pedals and gear shifter. The highest-grossing game of 1983, the game was officially ported to post microcomputer platforms of the time with many unofficial clones. 

Gaming was big in 1982, one mostly forgotten console that was launched that year was the ColecoVision. Selling strongly at launch due the bundled Donkey Kong game, this Z80-based system faded quickly and was out of production by 1985. Quite collectable today, a ColecoVision in good condition with games and accessories can cost you several hundred pounds.

Games consoles became popular in the 1980s, but the very first console was the Magnavox Odyssey launched in 1972. The basic but playable games were enhanced with accessories such as cards, dice and screen overlays. 350,000 Odyssey systems were sold over three years, today these are also very collectable with prices ranging from hundreds to thousands of pounds.

Taking another step backwards, 1962 saw the world’s first computer-controlled factory running on the Ferranti Argus industrial computer platform. Argus was originally designed for military applications, but it found its true strength in running as an industrial controller. Development continued into the 1980s, seeing use in everything from oil production to telecommunications, and importantly also in controlling nuclear power stations where they are still in use today.

Another technology designed originally for military use was the frequency-hopping spread spectrum. The concept was originally patented in 1942 as a way of preventing radio-guided torpedoes from being jammed by the enemy. A paper tape in the torpedo and guidance system allowed the radio frequency to change in a predetermined way, avoiding enemy jamming. This technology eventually found itself into Bluetooth and WiFi communications. Although this all sounds very dry, the inventor was Austrian-born actress Hedy Lamarr, who in addition to being one of the greatest actresses of her era was also a talented inventor.

While we are on the subject of war and weapons, the Gatling Gun was the world’s first widely-used machine gun, in service from 1862 with the US Army and finding its way into use worldwide until the early 20th century. The Gatling Gun marked the beginning of industrialised warfare and a technological arms race that continues to this day.

120 years later, 1982 saw another technological race as the computer systems evolved rapidly in every market from home users to research institutions. One of the leading companies of the time was Digital Equipment Corporation (usually known as “DEC” or just “Digital”). The DEC Rainbow was an attempt to compete for the same market as the IBM PC, running on both a Zilog Z80 and Intel 8088 processor, the Rainbow could run either CP/M or MS-DOS. Despite the “Rainbow” name, the machine was monochrome only by default, outputting to a monitor very similar to a VT220. Despite the support of one of the biggest names in the industry, it was not a success except for the iconic LK201 keyboard which was widely emulated.

Where the Rainbow was an attempt to create a new microcomputer from scratch, the DEC Professional was an attempt to shrink the PDP-11 into a desktop package. Although a promising idea, poor execution and market indifference let to its failure.

One of the more advanced machines of the time was the DISER Lilith, launched commercially in 1982 after being used as a research platform for a couple of years. Unusually, the Lilith ran Modula-2 and has a large portrait graphical display. Based in part on work done on the Xerox Alto, the Lilith was probably too advanced to be a sales success but remained influential, especially the mouse design which later influenced the first mice designed by Logitech.

If PDP-11s and the Lilith just weren’t powerful enough and you had very, very deep pockets you migth consider the Cray X-MP, launched in 1982 at an approximate starting price of $15 million. For that you got not only the fastest computer in the world, but also one of the most remarkable looks with a central processor core that looked like nothing else – complete with padded seats. The X-MP was a success, and there were a number of successors. Today, Cray is part of Hewlett Packard Enterprise.

The X-MP was a niche but successful product, as was the Bloomberg Terminal which was originally launched in December 1982. A specialist system aimed at stock market traders, the original terminal was a simple device that could connect to any type of financial data that Bloomberg could make available. Several generations followed, built on custom hardware and software. Today the Bloomberg terminal is still available, but the latest generation will cost you around $2000 per month.

Aimed at a rather broader market – which it failed to reach – the Jupiter Ace also ended up being popular with a very specific niche. Somewhat similar to the ZX81 in terms of hardware, the Ace had the unusual feature of running Forth as a programming language instead of BASIC. Forth was very well suited to simple computers, however it turned out that most customers wanted to learn BASIC instead. Despite making a splash at launch, sales were low and production ended in 1984. Today the Ace is very collectable with good examples selling for £1500 or even more.

1982 was a good year for computer systems that might have hit the big time had circumstances been different. The Sord M5 is one of those, an elegant Japanese system running on a Z80 with 16Kb of RAM, colour graphics and sound plus a cartridge slot. The M5 sold well in Japan, and saw some popularity in the UK (as the CGL M5) and Czechoslovakia. Locally-produced derivatives of the M5 also sold well in South Korea. Although it showed promise, by the time it hit the shops the market was becoming crowded and it didn’t last long. Working M5s in good condition can sell for £500 or more, and cartridges are worth around £50 to £100 or so.

Not all computing innovations are welcome. The world’s first computer virus – Elk Cloner – was also invented in 1982 by Rick Skrenta. This boot sector virus infected Apple II floppy disks, although it usually did no real harm.

One other technology product to come to market in 1982 was the CD player. The world’s first model was the Sony CDP-101 launched in Japan in October. In the rest of the world, the Philips CD100 was the first available model. Sales were slow at first due to the cost, but by the late 1990s and early part of the 2000s the CD player became the most popular medium for music.

A decade later, 1992 was a pretty good year for technology too. This was the year that Windows 3.1 launched, a significant upgrade to the first usable version of Windows – Windows 3.0 launched in 1990 – version 3.1 added more polish and stability. For many people, Windows 3.1 was their very first experience of Microsoft Windows.

Perhaps not many Windows machines of that era are memorable, but the IBM ThinkPad launched in 1992 had a reputation for good design, robustness and reliability. A strong seller for IBM, especially to corporate customers, the ThinkPad line was eventually acquired by Lenovo in 2005 and is still made today.

An ideal peripheral to complement your Windows-based laptop might be the HP LaserJet 4. An exceptionally reliable laser printer, it was also more compact than previous models, easier to maintain, faster and gave better quality printouts. The LaserJet 4 was capable of producing over a million pages during its individual lifetime, and although parts did wear out they could be easily replaced. It was easy to connect to a LAN via an optional network card, or you could use a parallel cable. Although seemingly obsolete today, aftermarket spares kits are still available indicating that there are still LaserJet 4 series printers still in use.

Not every computer of the time was a Windows or Intel-based computer. The Atari Falcon030 was the final evolution of the once-popular Atari ST line. Based on a Motorola 68030 CPU with a Motorola 56001 DSP supporting sound and graphics, the Falcon030 made a good games machine, was excellent for music and MIDI interfacing and came with a wide variety of expansion options. However, Atari was struggling and the Falcon030 was dropped just a year later. Around the same time Atari was working on the Falcon040, a 68040 power version. The Falcon is another collectable system, with prices for a good example being well in excess of £1000.

DEC was also coming up with innovative products in 1992. The DEC Alpha 21064 CPU was a powerful RISC processor designed for workstations and more powerful systems. Capable of much faster performance than Intel’s rival CPUs, the Alpha architecture saw some success in the 1990s but it faded away after DEC was bought out, first by Compaq and then by HP.

Another decade later to 2002, and mobile phones were becoming popular, and some of these were beginning to blur the line between a phone and a computer with the introduction of smartphones. The Sony Ericsson P800 was a Symbian-based device with a stylus-driven touchscreen and a camera, which is effectively one of the ancestors of modern smartphones today. Due to the high price and complexity, it didn’t sell in huge numbers but it did appeal to those who could see the advantage of having a computer in your pocket.

If you wanted something simpler and more robust, you could try the rubbery Nokia 5100. A weird-looking thing by modern standards, the 5100 comes from a golden age of phone design where every new model had its own distinctive looks. The 5100's key selling point was its robustness, although most Nokia phones of that era seemed pretty indestructible. 

Technology was coming to other more mundane devices as well. The Roomba is an autonomous robot vacuum cleaner, first introduced in 2002. Capable of cleaning a floor by itself and then returning to its dock to recharge, the Roomba is more of a pet than a domestic appliance – sometimes needing rescuing when it has gotten itself stuck on something. Twenty years of development have made Roombas even smarter.

Finally… well, a different sort of invention altogether. 120 years ago in 1902, the Teddy Bear was invented. Named after President Theodore Roosevelt, the teddy became the most popular type of soft toy of all time. Go and cuddle one right now.

2020: things that didn’t quite make the cut

This year we’ve covered gadgets and inventions from the 1800s and up. But there are plenty of other things that had anniversaries this year that we didn’t mention.

One of the most important inventions debuted in 1810 – the tin can. A key product of the industrial revolution, the tin can answered many of the millennia-old questions about how to preserve foodstuffs. More reliable and palatable than salting, drying, pickling and a variety of other methods this humble tin can meant food security for growing populations in the 19th, 20th and 21st centuries.

Also hailing from the nineteenth century was celluloid, a versatile class of materials that were pioneered in billiard balls in 1870, and then found their way into many other products from toys to films. However, celluloid’s habit of bursting into flames means that it is rarely used as a material today.

Somewhat related to celluloid is cellophane, a lightweight and flexible material that lent its properties to Scotch Tape, introduced in 1930. Also from 1930 – and perhaps a little bit more edible – is the Hostess Twinkie cake bar. Allegedly, Twinkies last forever – but eat a decade-old box at your own risk.

Fast forward to 1960 and the white heat of technology forges something even more high-tech than sticky tape and cake bars, with the laser. Don’t ask me to explain how these things work, they just do. Pew pew.

People who remember the home computers of the 1980s probably remember the Commodore VIC-20 – but it had an immediate predecessor in the shape of the VIC-1001 which was sold successfully in Japan only. The main difference between the two is that the VIC-1001 supports Japanese Katakana characters.

By 1990 of course things were really getting more advanced. The Sega Game Gear was an 8-bit handheld console that carved a significant market for itself. Another 8-bit games machine, the Commodore 64 Games System (or simply the C64GS) was a more traditional console based closely on the legendary Commodore 64 home computer. The C64GS held great promise with the potential of a huge games library, but it failed to deliver in a spectacular way.

In the same year, the Macintosh Classic breathed a bit more life into a familiar format at a sub-$1000 price point, but the 68000 processor was getting a bit long in the tooth by then. More powerful, but three times the cost, was the 68030-based Macintosh IIsi which was much more forward-looking.

Handheld gadgets continued to develop, and in 2000 the Sharp J-SH04 was launched in Japan which was the world’s first recognisable camera phone, with a rear-facing 0.11 megapixel camera. It wasn’t great, but it set a pattern that other early camera phones improved on.

That’s it for 2020, a difficult year for many people. Let’s hope that 2021 will be better. A big shout out to all those key workers, healthcare professionals and everybody trying to be socially responsible (or even just managing to keep themselves sane) this year.

DEC PDP-1 (1960)

First unit shipped November 1960

In 1960, the Massachusetts firm Digital Equipment Corporation (typically known as “DEC” or just “Digital”) was just three years old. Founded by two ex-MIT engineers, DEC’s earliest products were small computing modules on cards that could be used in labs, the design of which was based on work originally done at MIT.

The company advanced quickly, and in 1959 it announced a minicomputer based on these modules, which they called the PDP-1. “PDP” stood for “Programmable Data Processor” – according to legend this was because DEC was afraid that IBM might sue if they called it a “computer”, but in reality it seems that this approach was because computer companies were regarded as high-risk for investors, where lab equipment companies were less so.

Although clever and flexible in approach, the modules still consisted of individual transistors and other components soldered to a board. This meant that the overall system was quite large (weighing hundreds of kilograms). It was 36-bit computer with the equivalent of just 9.2Kb of memory, mass storage was provided by paper tape and output could be to a printer or weird circular CRT that had basically been transplanted from a radar system.

Prices started at $130,000 for a basic system (around a million dollars today) which made it a feasible purchase for well-funded labs, universities and tech-oriented companies. It was essentially a single-user system until the development of timesharing OSes such as the one from BBN. As a comparison, an IBM 7090 mainframe computer of the same era cost around $2.9 million ($20 million today), and although the PDP-1 was much less powerful it was much more flexible and it could be programmed to do things that were impossible on a tightly buttoned-down mainframe.

Things that you couldn’t do on a mainframe but could do on a PDP-1 included playing synthesised music and a key early video game – Spacewar!. A precursor of much later video games such as Asteroids, the game used the Type 30 vector display of the PDP-1 to show two opposing spacecraft fighting each other around the gravitational field of a sun. The Type 30’s long persistent phosphor added to the space-age gameplay and of course it became a major reason for people to book time on their department’s PDP-1 for (ahem) “research”.

Spacewar!

DEC were still a fledgling company, and although the PDP-1 was a success it only shipped 53 units. However, just five years later DEC was growing quickly and the 12-bit PDP-8 launched in 1965 shipped an astonishing 50,000 units over its lifetime, and five years after that the 16-bit PDP-11 eventually shipped 600,000 units. As an aside, DEC also made 36-bit and 32-bit computers in the 60s and 70s, to add to the confusion.

The architecture used in the PDP-1 turned out to be a dead end, ending in 1970 with the PDP-15. However, it helped start a revolution in small-scale computing which – after nearly two decades – allowed everybody who wanted one to have a computer on their desk. Unfortunately for DEC, they never could successfully transition from minis to micros, but that is another story.

RS-232 (1960)

Mouse using a serial interface
Introduced 1960

Known to many as just a “serial interface”, RS-232 is a surprisingly old communications standard that was once everywhere and even today it refuses to die. A simple way to connect a computer with a peripheral or other computer, the RS-232 interface could be used – with a bit of effort – to connect just about anything to just about anything.

The RS-232 interface is a “serial” interface because it transmits data one bit at a time in two directions, compared with contemporary “parallel” interfaces that typically transmitted 8 bits at a time in one direction.

The standard defines one end as the DTE (Data Terminal Equipment – e.g. a computer) and the other as the DCE (Data Circuit-terminating Equipment – e.g. a printer) connected together using a cable with 3 or more wires and terminated using 25-way D-type connectors. The number of wires in use varied depending on how many features you wanted to use, and many implementations ditched the large 25-way connector for something smaller, typically a 9-way connector on a PC.

Connecting DCE-to-DCE or DTE-to-DTE would require a special cable, and indeed it was possible to make custom cables quite easily depending on your needs, or you could simply use one of many adapters between different types of connector or equipment. Typical transfer speeds could vary between 50 baud (bits per second) to 9600 baud, 19200 baud or even higher.

A typical early use of RS-232 would be to connect a terminal to large computer system, or in later days a PC to a printer, modem or mouse. Indeed, on the PC the serial port lingered into the 2000s until the more versatile but fundamentally similar Universal Serial Bus (USB) became the de facto standard for connecting things together.

Because most computers either had a built-in serial interface or one available as an add-on, if you had (or made) the right cable then you could transfer files between utterly different and usually completely incompatible systems. The first challenge was to acquire a copy of an application such as Kermit and apply it to both systems, but once you had that it was a reasonably trouble-free way of moving data about.

Although RS-232 interfaces are less common than they used to be, they can still be found on industrial and laboratory equipment, communications gear and even home entertainment systems. But perhaps the RS-232’s most peculiar lasting legacy is this song
