Nascom’s very own Floppy Disc control card was quite a versatile device. It could handle either 5.25 inch or 8 inch drives, single or double sided and single or double density on systems with either 2MHz or 4MHz processor clocks! This made it suitable for both Nascom-1 and Nascom-2 systems. Connectors could be fitted for either 34-pin (5.25 inch – as shown in the above example) or 50-pin (8 inch) drive systems.

The disk control chip was the 1793 – quite a decent device at the time and more versatile than the systems used in most modern PCs. Several boards could be fitted on a single bus.

Nascom could supply either CP/M or Nas-Dos operating systems (as an optional extra, of course!).
