Huh. I guess I had it backwards, but I have used the IIgs-era gray 3.5...hmm.
True, true, unless you are doing lots of disk-disk copies, which
admittedly is a niche need indeed. Although, I've noticed that some
disk-copying software doesn't work with the superdrive correctly, it sees
it as a plain old prodos volume and not a disk, and in trying to restore a
800k disk image to an 800k floppy in the drive, getting an error something
like 'disk type mismatch'.

Yeah, it was fairly nice in my LC III+...

Nope, the only boxes it fit in were ones that utilized the LC-PDS slot,
which while it did extend briefly into the 040 line (LC040 admittedly),
those were all LC form factors with the LC-PDS deliberately added for
compatibility.
(Like Performa 475, LC 475, etc) One thing I'm not sure of, did the Quadra
605 have an LC-PDS slot or an 040-Direct PDS slot? They shared the form
factor, but Apple always seemed to keep the '040-direct' slot within the
Quadra/Centris line. I'm guessing it would have been LC-style if not
sheerly by design, there wouldn't have been room for most quadra-style PDS
cards in there.
So the card works in:
All 68k LC family computers (duh, doesn't include, say, the Power
Macintosh 5200 LC) Pizza-box LC, LC II, LC III/III+, LC 475, all-in-one LC
5xx.
All Performas derived from the compatible LCs.
Color Classic
Quadra 605.
All of these will run with 32-bit off, but of course if you have more than
8mb of ram to the computer, you will lose it when it's off. Also, some
newer apps complain when it's off (PlayerPro comes to mind).

One other thing I've noticed...while using cmd-control-reset will reset
the Apple IIe environment and not your computer, as soon as you exit the
environment, your computer will immediately reset. I wonder if this is
something which has always been present, or simply in newer system
versions...
