QuotePCW 2.1 Supplied with the PCW9512. Support added for the PCW9512 and its daisywheel printer.Does not include code to load *.FID drivers.Floppy drive support altered to support a system with a 720k drive A:. Also some tweaks made to floppy interrupt handling, perhaps to cope with slight hardware differences.[/l][/l]
