Make sure that the test floppy is unimportant and that you disconnect the drive if it is making suspicious noises. I could not find information about voltage either, so I have ignored it. The PS/2 supported 1.44 MB and 2.88 MB 3.5" floppies, but all of mine are 1.44 MB drives, and that's the same capacity of "standard" drive that I'd want to replace it with.)ĭisclaimer: I don't have enough experience to know which of these pins, if any, need to be NOTted in the converter.
(Assume both drives have identical capacities, so that once the electrical interface problems were solved, the software should work without a hitch. Anyone know of a source for a pinout? Better yet, has ever done this before and know that it works? Is there any way to adapt/convert this proprietary PS/2-specific connector to allow a standard 34-pin PC floppy drive to be plugged in? The data and power are both provided on the PS/2 connector, so there should be a way to build an adapter. Both are via Wikipedia, licensed under CC by-SA.) Right image adapted from original by Dale Mahalko. (Left image courtesy of Tomáš Slavotínek. The photo on the right is a better shot of the connector on the back. The photo on the left shows a front-shot of an OEM PS/2 floppy drive, just like the ones in my machines. Their floppy drives used a card-style "edge" connector that carried both power and data, and plugged directly into a slot on a daughter-board. Unfortunately (and quite ironically), the PS/2 series is not IBM-compatible. (Some of them even older than the broken PS/2 drives.) It would be really nice if I could just drop one of these drives in my PS/2s. However, I do have a pile of standard 3.5" floppy drives that work just fine. And have become extremely scarce in the intervening years. I don't have any "spare" PS/2 floppy drives, and even if I did, they would very likely be broken, too! For some reason, these drives just didn't hold up well. This gets old fast, especially for an assembly-language programmer! None of the floppy drives will read disks, which means all I can do is key in BASIC programs.
I have three different IBM PS/2 machines and all of them are in perfect working order-except for the floppy drives.
