The GX4000 was Amstrad's attempt to crash the console party in 1990. Built from the bones of its CPC Plus computer hardware, it added cartridge slots, hardware sprites and a richer palette of colours, and on paper it had enough about it to be interesting.
In practice it walked straight into a buzzsaw. By 1990 the 16-bit machines were busy redefining what players expected, and the GX4000's 8-bit roots looked instantly old-fashioned next to them. Starved of software and outgunned on every front, it never stood a chance.
It sold only a few thousand units and was discontinued within months, taking its place in history as one of the era's most striking flops. The GX4000 is a cautionary tale about turning up late to a fight: a decent enough machine, launched at exactly the wrong moment, into a market that had already left it behind.
