floppy tester - fault finder for floppy-disk drives

floppy tester elektor may 1984 Floppy-disk drives are fast becoming commonplace with the home computer. They are of necessity a fairly complex and finely engineered piece of equipment and, thankfully, they are reasonably reliable. However, in keeping with today"s world, they do fail on the odd occasion. The problem is that, when a failure occurs, it can be difficult to establish whether the fault lies with the floppy-disk drive or somewhere else in the system — be it hardware or software. The circuit here provides a quick and simple means of checking the floppy-disk drive for all operating modes. floppy tester fault finder for floppy-disk drives A floppy-disk drive is probably the most expensive single item of hardware (with the possible exception of the computer itself) that will be purchased for many home computer systems. It is of necessity a rather delicately engineered piece of equipment and should therefore not be dismantled without due cause. None the less, problems can a...
