Tatung Einstein was a computer made by Tatung in 1984, only available in the UK and Taiwan. It was often used to program ZX Spectrum, Commodore 64 and Amstrad CPC games. There was also an upgraded model called the Tatung Einstein 256 that is rare and resembles an MSX computer in looks and supports the video mode from the computer.
Despite that this machine was used to develop games, there were very few games actually made for this unit.
MAME is the only emulator for the Tatung Einstein.
