Wasn't this the ugly Spectrum based Sam Coupe?
There was also the Atari TT 030 and the Acorn range of computers.
funnily the Acorns reached RISC CPU levels and had a nice OS.
Atari didn't seem to go that far, not that I'm aware.
Amstrad did a Mega-PC too, a 386 with a built in Sega Megadrive
(Genesis) that was activated by sliding across a panel to reveal a
cartridge slot.
Amstrad always make nice looking products, but the hardware in them is
usually pretty crap.
:-D :-D
