Could run the CP/M operating system.

Bad points

Used 3 inch disc drives which in the event lost out to 3½ inch models (although a 3½ inch one could be used in the spare drive slot).
Too expensive for a home computer.

How successful?

Did not sell well.
It was not clear whether the Einstein was intended for the home or business markets.


Despite coming from a Taiwanese company the Einstein was in fact designed and built in the UK.
The specification was quite good but it was much too expensive to compete in the home market with the likes of the Commodore 64, at half the Einstein's price.
As a business machine it was a cheap option but by the end of 1984 business computers using 8-bit processors and running CP/M were seen as outdated.
