Amstrad GX4000

The Amstrad GX4000 is a portable handheld video game console released in the United Kingdom. It uses a Z80 CPU running at 6MHz, supports resolutions up to 256×256 pixels in 64 colours, and plays games on 3.5-inch compact disc read-only memory (CD-ROM) discs, which were also used by the Amstrad CPC and Amiga CD32 families. The system sold around one million units and was the UK's best-selling handheld during the later 16-bit era. This hardware item features a shoulder button gamepad and is physically compatible with the Amstrad CD32 AV cable for monitor output.
