    I have a UNIX computer with a 68000 processor.  I have heard that
the 68000 has a problem with restarting an instruction and thus virtual
memory systems are impossible (??).  I have also heard that the 68010
corrects the bug in the 68000, and that it is plug-compatible.  What I'm
wondering is, is it really 100% pin-compatible with the 68000?  Can I buy
a 68010, replace the 68000 in my computer and still run all of the exist-
ing software and have everything work?  Is it that easy?

    I know that there are other considerations for virtual memory operations.
All I'm interested in right now is whether it is possible to just swap
processors.
