Not quite endless, no. Anything that uses DMA can very likely not be made
to work. I assume certain restrictions re IRQs would also apply. Anything
that uses a memory range would fail, I would presume. 16-bit cards won't
work. What you could get to work are cards that are 8-bit and use I/O
addresses, possibly also an IRQ.

Now, this is pure speculation based on what I know about PCs and GSs. I
have _not_ seen Derek's adapter (although he talks about it on #appleiigs
.. stop by!), I cannot comment on the _actual_ features of the beast.

Anyway, even with the restrictions applying, that leaves things like Ether
cards, 2Mb/s floppy controller cards, 16C550 cards, some very old SCSI
cards, some GAL programmers and Eprom blowers. Out of these, I think only
Ether and maybe 16C550 actually make sense: SCSI is done by the RF and
Apple HS, and floppy controller is done by BlueDisk. You can only have one
of these beasts, so you might as well use it wisely :).
