Yeah, I'm probably throwing a bus error when I shouldn't, but I'm not going to change the code just yet. Maybe it should throw a bus error but GEMDOS doesn't handle it. (Maybe it's missing an ISR that just returns back without taking action.)

Probably what I'll do is attempt to detect the running OS and if I notice GEMDOS, then disable the bus error on the slots. Not really what a real Lisa would do, but it would make it more compatible. I have similar code for the mouse handlers which just peeks into the running OS to see what that OS thinks the mouse position is, but this would actually be an intrusive change.

Hey, it's a great start - that's one more OS than we've had available for the Lisa.
