Nearly nothing is known about these obscure CP/M systems. The technical info is related to the Mimi 802, and the picture illustrates a Mimi 803...

Mimi's at Leicester Polytechnic, by Rob Seaward:
I used one of these at Leicester Polytechnic around 1981/82.
We used to have a lab full of these for students - we were learning FORTRAN and were lectured by Roger Hutty who wrote a very good book in the subject.
I remember we used to boot the machine using a combination of keys (possible shift or control and B if I recollect correctly).
To ensure myself and a friend could always access a machine (particularly when we were close to assignment deadline) we swapped the V and B keys on the keyboard making the machine unuseable to any other student or for that matter the dumbfounded technicians.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
