I can’t find a photo of a Mimi 801 so here’s a photo of British Micro’s Mimi 802. 🙂
The GM801 was designed by Gemini and sold to British Micro (of Watford), who sold it as the Mimi.
It’s not really relevant to this site, but there’s a nice article (from which I stole the above picture!) here:

The design was based on a single board. There was a full 64k of RAM and 2 floppy disk drives. The system ran an OS compatible with CP/M.
British Micro went on to produce the 802, 803 and 804.
