Not sure on that, but mine were Seagate ST225s (I had a pair of them) half-height 5.25" HDDs.Is that what the victor 9000 had ? It had this funky floppy drive that had much higher capacity than the ibm at the time.
Do you mean a Bernouli Drive? Those were about 5.25" "floppy" looking discs (mylar in plastic cartridges). I had a 40MB version of that at one point.
