The official apple line is that virtual memory will not run on 68000 Macs that
have been upgraded to 030 by third parties. This is not out of spite, but
because they utilize ROM routines that do not appear in the Plus and SE and
Portable (don't know about the Classic). Presumably they could stick these
routines in the System and have them loaded into RAM to override the ROM
versions but the last I read (end of '90) they said they didn't want to do this
for some reason (maybe not enough demand or too much hard work).
