At the time I managed, with it, to read a 640K formatted CP/M floppy... well, almost. It would always read whole blocks, so there was always some garbage between original and current eof(). But even that won't read this 720k format because it seems the current BIOSes don't use INT3 anymore. So I'm looking for something from around 1998-2003 to still have old-style BIOS, but some disk or USB that's transferrable to today's boxes, just to read those 40 floppies.

>You might be able to find someone with an old machine from the period you specify. I have a running one from around 1997 which I fire up a couple of times a year - originally had NT 3.51 on it, then Win2K, now Server 2003 R2. It has a 3.5" floppy but never had a 5.25" drive.

I do recall one of those forehead slap moments *after* saving data on a 5.25" double-sided diskette on a single-sided diskette drive -- it was after I'd written data to the floppy did I notice that the diskette drive was a full-height type (which should've been a visual clue that I could very well be dealing with a single-sided diskette drive). Fortunately I had a copy of the important data on another floppy diskette.
