Superboard II

The Superboard II, also called Model 600, was quite the same board as the british clone Compukit UK-101.

It came in only ready built version and did not featured neither power regulation on board - User had to build or buy a 5V external power supply - nor RF modulator to display on a standard TV, but only a composite video output.

A 40 pin IC socket allowed an expansion board and OSI bus to be connected, giving access to memory expansion (up to 64 KB) and floppy drive controller.

See in the 'Read more' section a very interesting information about Mike Cheiky, the founder of OSI.

I have just dragged my superboard II out of storage and intend getting it up and running again. I spent many happy hours programming ms basic with this dinosaur and hope to do so again

I got one of these in 1979 and spent many many hours doing all kinds of things with it, programming basic and 6502 assembler as well as building memory boards and a disk controller. It has not been switched on for decades but it is still kept safe for a really rainy day!

I bought a Supper Board II in 1979 and built a power supply and TV interface for it. I programmed it in Basic and Assembly Language for several years..learned a lot from that Computer. I also used a Compac 386 for a few years traveling with it.
