Amstrad unveiled the GX4000 in Paris in 1990 alongside the 464 Plus and 6128 Plus computers, launching it in several European markets in September. It was the video-game-only version of the new CPC Plus architecture: it used a Z80, 64 KB of RAM, ROM cartridges, a 4096-colour palette and 16 hardware sprites. It shared much of its technology and cartridge software with the CPC Plus computers but omitted the keyboard and computer storage. Burnin' Rubber was supplied with the machine. It was Amstrad’s attempt to enter the European console market directly.
