IBM called them 2.88M, which is the formatted capacity when using a bogus definition of megabyte. (80 * 2 * 36 * 512) The dividing line between regular and obscure systems is not always clear. Some people claim that dual speed 1.2 was as common as 360RPM. Outside of the USA, 360RPM 3.5" wasn't as rare. 2.8M was popular in some niche markets, along with 20M floptical, LS120, Kodak/Drivetec 6? M, 12M? 5.25", Weltec 180RPM 1.2M with 250K data transfer rate, etc. 'course some of those drives used on PC's were not a "normal" SA400 style interface, including parallel port interfaces, and some used SCSI. And, of course, there are some with special harware that hardly ever were on PC's, such as hard-sectored, 2.5", etc. If this ever does make it to a website write-up, it should cover the "normal" ones, and have a paragraph listing the obscure and bizarre. That way, people with "non-standard" setups won't be excluded. -- Grumpy Ol' Fred cisin at xenosoft.com
