When I first started working at Software Results in the Fall of 1984,
me and one of the other student workers were marveling at the
32-bitness of the VAX-11/750 (with 8MB of physical RAM in a 4GB
virtual address space) and trying to envision how expensive and how
large *Four Gigabytes* of RAM would be, and it was *immense*.

This same machine (8MB RAM) could handle 70 dumb terminal users, but
to be fair, it did swap a bit over 40 users.  The two fattest apps we
had were were VMS MAIL and MASS-11 (word processing).
