no other hardware would want the PC joystick interface.
I don't think you'll find many takers on that. 8-)
(I dunno, this may be shareable, but it's a PC motherboard
thing, not really an ISA thing, isn't it?)

The console interface, including mouse stuff, is currently
machine-dependent. These (at least pms; i'm not sure there's
use in sharing the other two) should be shared in the long

same as lms/mms/pms, except more so. I can't use this
on e.g. the Alpha, because, well, i have more things than
VGA as my console, and this just isn't suited for that world.

"wrong!" see above.

ahc_isa.c isn't a 154x driver, nor is it 'really' an ISA driver.
Care to come up with some more examples? 8-)
It's worth noting that, in the long run, i would like to see machines
share a common console interface, but that's a long, hard road, and
there's a long way to travel on it before we'll be there.
