Situation: public
The M5 made its first public appearance in May 1983 at the Midland Computer Fair, held in Birmingham’s Bingley Hall where Sord staff said - ahem - the computer would now not be available until June. Still, the M5’s appearance allowed eager punters to get their hands on the machine. They found themselves with a compact unit stylishly formed from grey and black plastic. The black-on-black keys were of the ZX Spectrum type, but marked with white alphanumeric and cursor characters, plus yellow graphics glyphs and Basic keywords. There was still no room for space bar though. Back from the keyboard, the entire top of the M5 flipped up to reveal a warm yellow surround for the Rom slot, and assorted instructions printed on the inside of the (removable) lid. Later models, some made in Ireland, others in Japan, even after the CGL rebranding, replaced the yellow plastic with the M5-standard pale grey.
Round the back of the machine: the customary power, tape, game controller and TV modulator outputs, plus novel composite video and mono audio RCA jacks for alternative telly and hi-fi linkage.
The colour scheme, said Personal Computer News reviewer Richard King, gave the M5 a “faintly military look”, and the M5 remains one of the more aesthetically pleasing 1980s home micros. Possibly one of the better built ones too: “The general construction is of a very high quality,” wrote King. “It feels solid, almost rugged, and would doubtless stand up to considerable rough treatment... There are proper connectors for everything, so no more problems with power supplies which spend most of their time delivering 5.5V to the carpet.”
Don Thomasson, writing in Computing Today, also gave the M5 the thumbs-up for its “competent and attractive” construction and design. Others praised Sord’s incorporation of a metal shield place over the motherboard to minimise radio interference, something other vendors should perhaps have taken note of.
Reviewers praised the video presentation. King, for instance, lauded the M5’s “frankly impeccable” display, which he found to be “steady and clear, with good definition and well-separated colours. Compared to the tatty output so often associated with lower-end/home machines, it was a pleasure to use”.
It had some clever features too. Personal Computing Today regular Chris Palmer spotted the Basic I - ‘I’ for integer - HEX$ function for converting decimal numbers into their hexadecimal equivalents - handy for machine coders - and useful character codes such as CHR$(4) and CHR$(6), which auto scrolled the display a character width left and right, respectively.
“You might not realise the significance of this,” he wrote, “but you will realise that the biggest hurdle to overcome is how to get the screen scrolling sideways. With the Sord, this can be achieved by printing these control characters and letting the computer do the hard work.”
Users of many other systems had to write machine code routines called from Basic to do this. I did for mine.
But Palmer was not unreasonable disappointed by the lack of available Ram: “Offering only 4KB of useable memory is a very serious crime indeed.”

CGL promotes the M5
Computing Today’s Don Thomasson was less concerned by that because of the scope for expansion. Instead, he decried what he considered the M5’s poor documentation: “The M5 is complicated enough to produce confusion, and the documentation fails to provide enough information to escape from this state. A minor keying error can produce bewildering results, and though there may be a recovery route it may not be obvious.”
Richard King wasn’t keen either: “My only reservation is over the documentation, which suggests that there is considerable untapped potential in this machine, but then fails to provide the keys.”
But overall the response was positive. Chris Palmer was typical. On the basis of his time with the Sord M5, he said, “as the Japanese have a talent for making good products on the cheap I think it is going to be very difficult in the future to remain patriotic and buy British.”

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...

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.
