And they're pretty common on non-MSDOS systems. I far more 80-track DS
drives than 40-track of any flavour. There are also 2.5" disks, though the only ones
I've seen were made by TDK
for an early digital camera. Anyone remember the make? Canon?
I think that they
may have been Zenith. In my original message that
started this thread, I explicitly asked if anyone had any available.
