- Best one IMHO is VMM v3.x. You will find it on Aminet. But it won't
- run with a 68000, of course.

- You're speaking about a bus error. An address error is generated by
- accessing an odd address on 68000 and 010 CPU's.
-
- You will need a 68010 at a minimum to support virtual memory. The
- 68000 doesn't support instruction continuation and the information
- in the exception stack frame is not sufficient for simulating an
- access.
