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?
It would be nice to get a hold of three or so extra auto-inject floppy
drives for some vintage macs. But they seem to be expensive and hard
to find. I noticed that the external 3.5" floppy drives for the 2gs
seem to be plentiful. Are they the same mechanism?

The HD macs had a different chip in them then the DD models. There were kits
to modify units to be able to use the HD superdrives. I think you can use DD
drives on units equipped for HD but I am not sure.
The IIgs used DD superdrives. There were some aftermarket HD drives for the
IIgs but you needed a special controller and those drives are more expensive
then a HD superdrive would be for a mac.

Great! So I could possibly find some ratty 3.5" external 2gs drives,
disassemble them, and drop them into, say, a IIfx or IIci?

All the Apple made IIgs drives I know about are DD.

The IIgs used 800K drives ("Apple 3.5 Drive"), but they weren't
"superdrives". You could plug the Apple 1440K "superdrive" (AKA FDHD)
into the IIgs, but then it only acted as a 800K drive. You could plug
them into the Apple Superdrive controller card to actually use them as
1440K.

I'm not surprised that there were some third-party drives, but I can't
imagine why anyone would have paid more for a third-party drive than for
the actual Apple drive.

Sure, but they would only be 800K.

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???'

So the cable matches the drive or the cable matches the motherboard?

I believe the cambe goes with the drive.
IIRC, the original 400K SS drive had a cable with all pins wired. The
800K drive had at least one fake wire, and the 1.44M dirve had more than
that.
