===== History and Trivia =====

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.
