This is the only Kemitron model of which I have a picture, and in fact a full advertisement with specification. (Advertisement from "Electronics and Wireless World", April 1985 issue.)

The specification of the Kemitron Solo is:

Processor:  Z80A, 4MHz.

RAM: 64K, expandable to 128K.

Storage: Single 300K Floppy Disk Drive, Second Drive optional. Optional RAM Disk.

Interfaces: Dual RS232. Five Expansion slots. RS422 and IEEE interfaces optional. Analogue and Digital I/O cards also available.

OS: CP/M 2.2.

The fact that it had a RAM Disk is unusual, and cutting edge for the time - no doubt driven by its principle use of high-speed laboratory data collection.

It is difficult to say from a picture, but the expansion slots could be for International Sized Cards (4.5" x 8"). This could be the computer I have cards for!
