there where at least three typce of IBM, some only 720, some only 1.44
(though the could be convinced...) and the dual version. Having had PS2
as in the early base 8088 version and the non ISA bus versions.
Much weirdness.
The standard 1.44 drives also do 720k. Just use
the right media with
the hole in the right place.
"standard"??!?
That might preclude some IBM 1.4M drives, particularly PS/2. OK, you can get away with saying that those are NOT
"standard"
They did not HAVE the media sensor, and relied on RWC (Reduced Write
Current) signal from the FDC, instead of in-drive sensor and switching.
;) Fred you and I know using standard and floppies in the same sentence is
asking for pain. PC (help me here) standards were best at making it worse.
