The “Chas” board by LJ Electroncis is an evaluation board based on the Motorola 68000 CPU. It is designed to allow the user to test circuits to a CPU and check they preform as they should. This allows easy checking of designs prior to production.
Given the date on the IC’s, this computer is from 1995. It has a floppy drive controller, keyboard, video output, RS232 serial interface, Centronics interface and many other IO capabilities. Two additional EPROM IC holders are abailable for extra programs.

Does anyone have ANY technical information for this machine as I have one, with no manuals!

Did you ever get any information? I have one too but without any documentation.
I can format a disc but without more than the on-screen help, it’s a bit tricky!
