I used even 800K for DS/DD media.I vaguely remember using a 5.25" 720K disk format on a 8088 back in the 80's - does anyone remember this? Maybe I'm not remembering it right.
You can tell your system that your 5.25" HD drive is a 3.5" DD drive, and you'll get a 720K format as well.I vaguely remember using a 5.25" 720K disk format on a 8088 back in the 80's - does anyone remember this?
5 1/4" "quads" won't necessarily work in a vanilla pc though. The Tandy 2000s Mitsubishi 4853-1 floppy drives will not work in a Tandy 1000, this I know. Some more or less standard IBM workalikes used dd drives that wouldn't work in a standard clone either. The Leading Edge model m comes to mind. The TIPC, though not a true IBM compatible, also used non standard Epson drives link.
AT&T 3B2s also used 720K 96tpi
Of course... are you a mindreader?Do you mean other than a 3.5" drive and a controller capable of 500Kbps?
AT&T 6300s (ie. Olivetti M24 and rebadges) had this as a DIP switch option. It came disabled for obvious PC compatibility reasons.
