While the 68010 _did_ support demand-paged virtual memory, I, too find
it hard to believe the 7300 was the *first* system to support it.  I
would think that at the very least, some flavor of UNIX, be it 4BSD or
System III on a VAX would have beaten the 7300 by a number of years.

I'd wade through old distros and check myself, but my PUPS archive CDs
and my genuine AT&T SysIII tapes are at home.
