A few other suppliers of hardware & software decided to start producing stuff for the Nascom and Gemini systems. There weren’t all that many, but there was some good stuff around.
Some of this equipment was sold under the Gemini name at some time, but may also have been produced under it’s own name.
A company called MAP 80 Systems Ltd, in particular, started to produce a range of cards for the NASBUS. Starting with the MAP-80 RAM card they added a CPU card, the VFC video & floppy controller and the MPI multi-purpose interface (which connected hard drives as well as floppy drives).
