SAM Coupé

~ the goodbye ~

Miles Gordon Technology was founded in June 1986 in Cambridge by Alan Miles and Bruce Gordon, both of whom had worked at Sinclair Research and both of whom left once Sinclair sold the ZX Spectrum to Amstrad. Their first products were disk interfaces for the machine they had helped build, the DISCiPLE and then the cut-down +D. Both carried a button that fired a non-maskable interrupt, which froze whatever was running so you could dump it to floppy, and that button is most of why the company had a reputation among people who owned a Spectrum and were tired of cassettes.

The SAM Coupé went on sale in December 1989, by which point MGT had moved to Swansea and floated as a public company. It ran a Z80B at 6 MHz with 256 or 512 KB of memory, expandable to 4.5 MB, and it had a ZX Spectrum 48K compatibility mode so an owner upgrading would not lose the software they already had. Sound came from a Philips SAA1099 giving six channels in stereo. There were MIDI ports on the back, and a 3.5-inch floppy drive could be fitted into the case rather than bolted on as an afterthought.

The problem was arithmetic. In December 1989 the machines people bought were the Amiga 500 and the Atari ST, both of which had been on sale for years and both of which were 16-bit. The SAM sat above the Spectrum it replaced and below the machines it was actually competing against, and commercial software houses did not write for it in any quantity. Roughly 12,000 units were sold across the entire production run.

I was five when it launched and about nine years off my first modem, so none of this reached me while it was happening. What reached me later was the archive. British 8-bit material sits in the same emulator directories regardless of how many machines a platform sold, and the SAM turns up there next to hardware that outsold it by two orders of magnitude, indexed the same way, findable the same way. By the time I had a dial-up line in 1998 the machine had been discontinued for six years and existed as disk images.

~ the breakout ~

MGT's reasoning was not stupid. The Spectrum had sold in the millions in Britain and a large part of that installed base was still there in 1989, still loading games off tape. MGT had spent three years selling those exact people disk drives. A machine that ran the old software while offering a real disk system and a proper sound chip looked like an obvious next purchase for a few hundred thousand households. The company went public in July 1989 on exactly that reasoning, six months before the product existed.

The press treated it seriously at first, then less so. Your Sinclair ran a piece in August 1990 headlined with the question of what had actually happened to the SAM Coupé, which is not the coverage a machine wants eight months after launch.

~ how it actually ended ~

MGT went into receivership in June 1990, six months after the computer went on sale. The brand was then restarted twice. SAM Computers Limited picked it up first. In November 1992 a company called West Coast Computers, spun out of the magazine publisher Format Publications, took the line over and kept building machines for an audience that was small and getting smaller. West Coast lasted until liquidation in 2005, by which point the SAM had been a hobbyist object for more than a decade.

~ the long tail ~

Twelve thousand machines is a rounding error next to the Spectrum's millions, and it is also small enough that the people who owned one largely still know each other. The SAM has the afterlife that only tiny platforms get: a preservation site that catalogs every company to have touched the brand, and new software still being written for hardware that stopped being manufactured before most of its current users were born.

The SAM Coupé is what happens when you build the correct machine for a market that has already left. Every feature on it answers a complaint Spectrum owners were making in 1987. By December 1989 those owners had stopped complaining and bought an Amiga.
