The //e doesn't have an MMU. There are just soft switches, addresses in the $C03x range you hit to switch banks of RAM. Works the same as the Language Card on the Apple][.

Well, it does. That's what Apple calls it. But it's not the same as everyone else's MMU.

Unix may not be impossible on a 6502, but you'll find it a real challenge. Akin to going 160 MPH on a flat-head Indian. Speaking of hopping up underpowered machines, there are 68000 CPU cards that go in an Apple//e slot. Run the kernel on one of those and the UI on the 6502?

Since starting this topic, I've decided to set my goals lower to a simple task-switcher. Much easier, and there have already been some written.
