Buy some junk
systems, parts etc. and take them all apart saving the
screws, and I would not even slow down at 100, maybe around 3,000. ;) The
floppy drive in the subject line makes a good screw donor too.
Problem with that method... I'll have it halfway apart, say 'Hey, it's a
trivial fault, I can fix it easily', spend the next day or so fixing
said (non-trivial) fault and _still_ need to get some screws :-) :-)
"BEING" one of a half a dozen extra 5.25 floppy drives is more than a
trivial fault, its a terminal illness. ;)
