I actually bought the Nova network that was there too! I have the Nova 2,
Nova 3 with the Nova-PDP 8/S link, Ken-Net and all the original software and
docs. The Nova 2 has a graphics interface and IC tester, Kennedy 9800, and a
diablo 42. The first memory expansion study was called "8K Interface for
PDP-8S with memory protect (A study in frustration)", by John Elton McFee,

BTW I wasn't BORN yet... doesn't that age me!

To give you an idea.. Focal 1969 outdates me!
