You seem to have gotten a lot of bad responses to your problem in this
o It is very rare for more than one component to die at the same time.
o I'm sure you didn't want to be told to build a funeral pyre.
o When the motherboard goes, the drive doesn't behave as yours did.
o As you told us, you already tried to boot off floppies.
o blah, blah, blah. :)
Apple had a problem with some HD20s made by Sony. It sounds clearly to me
by your description that this is the problem. I had the same problem. At
one point, Apple was replacing HD20s with HD40s for free. You can call an
Apple dealer to find out if your friend's serial number matches the
defective lots. The problem is stiction, by the way; the drive sticks on
startup. Sometimes a sharp rap to the side of the case will free the disk.
The sticking can vary with weather, too.
I doubt if Apple is still fixing this for free, but in the meantime, you
can disconnect the power supply to the internal hard disk drive (the thin
wires with the white plastic plug) so that you will be able to boot off a
floppy. If you unplug the entire HD20, the mac will no longer be internally
terminated properly. I would suggest a new external (or internal) hard
drive though. Hope this helps.
