The '''Tatung Einstein''' has characteristics very near those of the MSX machines (same video modes, same sound chip, sprites, etc.) but runs under Xtal/DOS which is not an operating system compatible with this standardCP/M. It was built in the UK at Tatung's plant in Telford in Shropshirepossible to connect an other floppy disk drive and a 80 column card was available.

The Einstein runs under Xtal/DOS which is an operating system compatible with CP/M. It was possible to connect an other floppy disk drive and a 80 column card very attractive computer but it was availabletoo expensive to have great market success.

==CPC generation== This computer have some similarities with the Amstrad [[CPC ]] (but also with [[MSX]]).:

The Einstein 256 casing is not quite unlike a CPC664 casing... The keyboard features arrows and Function keys, the built in 3" diskdrive is on the right.  <br> This computer was used for cross development purpose before PC and AtariST became the norm.
