Re: only ones saved
Ye Ghads! One of my very first jobs was Beta Testing controllers for the 2.88s. IBM said vaguely "wouldn't it be nice if we had double the capacity for Floppy Disks?" and TEAC and Fujitsu went about killing themselves, and each other, to make it.
My "Primary OS" at the time was SCO Enterprise, with NT 3.51, Novell, DOS 4/Win 3(something?-ish?) ,Slackware 1, and OS/2 on it ( was busy in my teens, and my machine was all SCSI, so, xNIX) which found and used the drive no problems. OS/2, no sweat. All things Micro and Soft required a damned hammer for the drivers and still wouldn't just sense and use the {edited, this is a family site} drive gemoetry and the controller Tom-Foolery (where waranted).
My first lesson in: The hardware *works*, these drivers blow. Then came ZIP Disks, which just sort of "Worked"...put that demon to rest.
