A discussion is underway with respect to the future of the various ISA

Check with the M68K people however. 3c501 won't matter to them but I'm
not sure which of the other chips ended up on Amiga ISA bridges. I know
NE2000 clones did.
I know you've currently got that "almost ne2k" driver that runs IRQ-less. Are
there other "ISA-like" onboard devices in the M68k harware scope that rely on
existing (x86) ISA drivers?
IIRC, the only m68k machines (supported by Linux) with ISA slots are:
- Q40/Q60, probably used with NE2000 cards only,
- Various Amiga bridgeboards, none of which are supported,
- Apollo DN, used with a 3Com 3c505 ISA Ethernet card (preferably the
version with an Apollo boot ROM), but the (changes to the existing) driver
never entered mainline, witnessed by the orphan APOLLO_ELPLUS config
option we removed a few years ago.
Apart from that, several "ISA" (Ethernet) chips were/are used, as
typically that's
the simplest solution to add peripheral support to a CPU local bus using a
minimum of glue logic.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
