Right, but I was wondering if there was a range of numbers assumed to be disk, the way 4 and 5 (and maybe 6 and 7?) are assumed to be printers. I know the Commodore drives were usually hardware switchable among device numbers 8, 9, 10, and 11... >> all you know is that >> the last operation wasn't to disk. > > Not even that.

Fair enough, but TTBOMK there were no drives actually manufactured for Commodore machines that had unit numbers below 8. -- Mark J.
