Lucas were remarkably late with their disk system. Several others were already available (some already using CP/M) so they were off to a difficult start. They designed a completely new controller card using the WD1793 control chip, capable of handling up to four floppy drives. It was capable of driving 8″ drives but was only ever sold with 5.25″ units.
