Gemini Galaxy

Gemini is a company derived from Nascom. The Galaxy models were as flexible as the S100 computers but had a proprietary BUS. They were usually CP/M compatible, so the same base library can be used, but extra functionalities are available.

Library extras include the graphics support (160x75).
