It's my understanding that the 020/851 pair's instruction set is a superset
of the 030.  If this is in fact true, it's probably impossible that any
system release could possibly do anything but provide the same features.
As a matter of fact, some software had the opposite problem (A/UX 1.0 and
Connectix' Virtual 1.0); they worked only on 020/851 machines, not 030s.
