Sord drawn: The story of the M5 micro
The 1983 Japanese home computer that tried to cut it in the UK
Feature It took Japanese micro maker Sord more than six months to launch its M5 home computer in the UK, but in April 1983, the company said the Z80A-based machine would finally go on sale during the following month - half a year after it was originally scheduled to arrive over here.
It was a bold move. Even in November 1982, when the Sord M5 was first scheduled to debut, the UK home computer market was becoming uncomfortably congested. More to the point, it was dominated by British firms: Sinclair, Acorn and Dragon, and Tangerine offshoot Oric and Camputers were both gearing up to release home micros of their own. Oxford’s Research Machines dominated the education micro market.
There were overseas computer makers who were successful over here in the home market: Commodore primarily but also, though to a lesser extent, Atari and Texas Instruments. Apple was selling its pricey II to business buyers, and IBM was starting to do make inroads into the same market with its 1981-launched PC.
But the Japanese? They were nowhere close. Only Sharp and Epson were making any headway in the business micro market, but neither they nor their fellow firms were attacking the home arena. It was arguably a point of pride among native computer companies that this was the case. They were adamant that they were not going to let Japan’s major electronics firms destroy the UK home micro industry they way the Japanese had smashed domestic hi-fi makers.
Sord Computer Systems was no Sony, JVC or Sharp, of course. It was founded on 15 April 1970 by Takayoshi Shiina and his mum, and in its first ten years had become one of Japan’s fastest growing firms - the fastest, it claimed at the time - thanks to its success selling business micros on its home turf. Sord, by the way, came from ‘SOftware haRDware’, Shiina said in a 1979 interview with the Sydney Morning Herald. When the company opened a beachhead in the UK early in October 1982, it was forecasting an annual turnover of £40 million - equivalent to £167 million now, depending on how you measure it. To put that 1982 figure into context, Sinclair Research reported revenues of £27.17 million for the year to April 1982, rising to £54 million during the following 12 months.
Sord’s pitch to British home computer buyers was typically Japanese: a machine clearly designed for playing games rather than thrashing out your own code, or running a small business. The stylish M5 had a prominent Rom cartridge slot and came with a pair of Mattel Intellivision-style wheel-based games controllers. Like other home micros it supported the Basic language, but the interprester came on a cartridge rather than a firmware chip within the machine. The M5 packed 8KB of Rom for its operating system. Other cartridges allowed it to run PIPS, Sord’s business automation system.

By the late 1970s, Sord was punching out business micros
The M5 spec was suitable games-centric too: only 4KB of Ram but an additional 16KB dedicated to the video sub-system. The resolution wasn’t spectacular but it was comparable to that offered by other micros of the time: 256 x 192, with 16 colours. But it had the capability to run 32 separate 8 x 8 or 16 x 16 graphic sprites - a facility then only offered by the Commodore 64, at that time as readily available to Brits as hens’ teeth, and the Texas Instruments TI-99/4A. It had four-channel sound too - three for tones, one for “noise” - and its processor ran at an impressive (for the time) 3.6MHz. Handling the video was a Texas Instruments TMS9929A chip. It had the same sound chip, the TI SN76489A, as the BBC Micro.
When Sord took the wraps off the M5 in the UK at the end of October 1982, the machine had been on sale in Japan for less than a month but had already notched up a software library of 60-odd applications and games, the company claimed. Sord said the M5 would cost around £150.
Inevitably, it was a no-show. Due to go on sale here in November 1982, by mid-December Sord was pointing to a February 1983 release instead. Most likely, the parallel attempt to establish the M5 in the US, which saw the M5 debut there as scheduled, along with the M343, an Intel 8086-based MS-DOS machine, took all the units Sord had earmarked for Blighty. Exchange rate fluctuations and other factors saw the price now listed as £169, though it would now come bundled with three cartridges, Sord promised: Basic and a couple of games.
Sord also had an eye to the broader British micro market. Come March 1983 there was still no sign of the M5, but the Japanese company had by now signed a distribution deal with Loughton, Essex-based Computer Games Ltd (CGL) to allow it, as CGL Chairman Paul Balcombe said at the time, to “concentrate its efforts on promising its business computer range”. CGL had experience importing Japanese handheld videogame devices. It would later be acquired by Amstrad.
That was still in the future. Now the question was, would the M5 ever be released in the UK? Toward the end of April 1983, Sord President Takayoshi Shiina flew into the UK to state that, yes, the M5 will go on sale here, in May. Oh, and it’ll now cost £190 - £189.95, to be precise. By way of some sort of compensation, the M5 would gain the ability to take extra memory, to be made available in 16KB units from July, Shiina said.
Some punters might have preferred to wait a little longer. Sord also announced it would offer the M5 Turbo, a faster version with “at least” 64KB of Ram in October, the same month in which, it also promised, it would ship a 16-bit business machine, the M12. Impecunious kids exasperated by the M5’s pre-release price rises were offered the prospect of a low-cost games-only machine, the M2, due to arrive in August. Sord even boasted it has a battery-powered portable machine not unlike Epson’s HX-20 in the works. It would go on sale in September, the company promised.

Re: 4KB RAM ?
"Stingy" - yes, when machines with 16K, 32K or 48K were relatively common, but...
"the machine had been on sale in Japan for less than a month but had already notched up a software library of 60-odd applications and games"....
Back then we could be genuinely creative with such "stingy" amounts of resource. A lot of developers these days would probably struggle to achieve much more than a simple "Hello World" if restricted to comparable resources.
Kids these days...don't know they're born....etc...etc...
Re: 30th anniversary of every man and his dog releasing a Spectrum-basher
ARM, which started life as a project at Acorn, the manufacturers of the Atom, BBC Micro and Electron.
Acorn didn't die, it evolved by designing a chip they wanted instead of compromising on an existing processor.
And didn't it work out well!
Funny the think the low power consumption was actually an accident of design!
Re: 30th anniversary of every man and his dog releasing a Spectrum-basher
But the interesting point is that *the UK had a consumer computer industry.*
The machines were designed and (usually) built in the UK, by British talent.
With the possible exception of the RaspPI, kind of, and a few app developers, there's no equivalent British consumer tech today.
Admittedly the sector turned into a classic bubble - first in, first out, blood on the dance floor.
But it's pretty much unthinkable now that we could field a market-leading British mobe, tablet, games console, 3D printer, laser cutter, toy robot. etc, etc.
What went wrong?
30th anniversary of every man and his dog releasing a Spectrum-basher
There seem to be a *lot* of these "30th anniversary" look backs at microcomputers just now. That's not surprising though, because it was around this point that the home computer market exploded (due to their becoming cheap enough for the man on the street and not just the rich hobbyist). Everyone saw the money to be made and started jumping on the bandwagon.
There were a frankly ludicrous number of home microcomputers being released back then. I have a load of my Dad's old "Your Computer" magazines circa early 1982 to late 1984, and each month there's a review of at least one new computer, frequently two and sometimes three.
Almost all these machines were incompatible, and even then people cared about having a machine that had good software and peripheral support. It would have been obvious to anyone that the market couldn't and wouldn't support them all and that the vast majority would fail- and they did.
In the UK, the ZX Spectrum dominated mainly because Sinclair was the first to release a colour/sound/hi-res computer at that price point. The network effect made its success self-reinforcing and made it harder for the "me too" competitors like the Oric-1 (and countless lesser-known machines) to break its stranglehold, even after it was outspecced.
The C64 did well at a higher price point, and Amstrad's CPC was surprisingly successful for a late-era entry, but aside from a few lesser-supported and/or niche formats (like the Atari 8-bit and BBC), the vast majority of those other computers had disappeared without trace by the mid-80s, never having gone anywhere.
Re: 4KB RAM ?
Run, don't walk, to TI's web site and order one of these.
https://estore.ti.com/MSP-EXP430G2-MSP430-LaunchPad-Value-Line-Development-kit-P2031.aspx
$10 gets you a programming/prototyping PCB, two MSP430 microcontrollers, an optional external clock crystal, and a USB cable (international airmail postage included). The MSP430 is an elegant little 16-bit processor with about 8kB of program space and 1/2 kB of RAM (the two microcontrollerrs you get are of different specs). Linux support is impeccable, with a port of gcc and the programmer-debugger both in Debian; or you can use TI's own IDE for Windows.
The MSP430 runs at up to 16MHz and has a bajillion different integrated peripherals. (Including a built in temperature sensor!) It consumes basically no power. Unlike the PIC the architecture is simple and is a joy to use --- writing machine code for it is surprisingly fun.
Downsides are that it's a 3.3V device, which means interfacing the Arduino's 5V peripherals to it can be a pain, but it's not *that* hard and there's enough 3.3V stuff around that you don't need to. Plus they've just put the price up --- it used to be $4.30.
I have most of a CP/M emulator written for one, using external serial RAM for working storage. It's a really nice feeling using a machine small enough to be comprehensible again.
