A couple questions...
Are there any differences between the double density and high density
auto inject floppy drives? That is, could I put a high density drive
in an older classic mac and expect it to work?
One thing to watch for are the little 20-way Apple ribbon cables that
link these drives to the mainboard. They are not what they seem -- in
particlar 1 ro 2 wries are not wires at all, but solid plastic, so those
pins of the connectors are not linked. If they are, then all sorts of odd
things happen (Eject motor runs continuously???)
I beelive there are at least 2 versions of the calbe (for double sided
and high density drives>?, with different coloured pin 1 tracers. A Mac
enthusiast may know more.
I found this out the hard way 'Why is that pin at totally differnet
voltages at the 2 ends of the cable???'
