The Superboard II, also called **Model 600**, was quite the same board as the british clone [Compukit UK-101](/museum/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.
