Old computers don't get much more obscure than the Sam Coupe, which was designed and built in Wales around 1989 by MGT. It had 512K memory, and a Z80B CPU running at 6MHz (not bad specs, for the era) it might have been the logical upgrade for Sinclair ZX Spectrum owners everywhere, if only the software houses of the day had taken a little more notice of it. Now it remains something of a historical conversation piece.
