Be careful. IF you get a situation where that drive shows you the
previous DIR,
instead of the current one after changing
diskettes, don't write
until the OS knows it.
^C (Ctrl +C) will tell DOS that the disk has been changed.
It's documented in CP/M, and undocumented in MS-DOS.
"Disk Changed" was pretty uncommon on 360K drives. More likely, it's
"READY" on pin 34.
I do have at least one pair of full-ht 5.25" drives that actually operate a
microswitch which I'm assuming is connected to that pin...
Most of them didn't, though.
