Be aware that you will also need a different
controller, or some minor
modifications.
PC controllers normally support 250,000 bits per second ("360K",
"720K"),
and 500,000 bits per second ("1.2M, "1.4M")
SOMETIMES 125,000 bits per second for 5.25" SD/FM.
2.8M runs at 1,000,000 bits per second.
Such controllers exist, but are not very common.
Fred. They've been fairly common since the 496 days (I've got several
machines with the controllers on them, including a 486 VLB system).
They kind of died out during the P2-P3 days and I don't know if I've got
a P4 system with that capability.
Of course, the media is darned near unobtainium, so the question is
somewhat moot.
But the drives themselves usually have more configurability than the
usual FD235HF drives.
