I had two floppy drives that I mounted in an external case. Then I hooked up an old switcher supply I had to it (this thing has no load protection, right? :-) and promptly blew both my floppies. Anyway, I bought two new floppy drives, mounted them in the case, and now I'm about to build a linear supply for it. One drive is a 1/2 height 5.25 and the other a 1/2 height 3.5 inch. Does anyone know what the typical current draw is on a 1/2 height 5.25 inch drive? How about a 3.5 inch drive? IBM XT Tech Ref says 900mA on 12V and 600mA on 5V, but these are for a full height floppy. I was hoping 1/2 heights draw less than full heights... Will one TO-3 packaged 7812/7805 pair do the trick, or will I have to use multiple TO-220's? -- Dennis Lou | dlou@ucsd.edu | "But Yossarian, what if everyone thought that way?"
