and have been quite interested in the high capability PDPs like the
PDP-11 Series for starters. I didn't know there were PDP 12 Series
computers. Are there other PDP series computers as well?
A good reference to the complete PDP range is "Computer Engineering: A
DEC View of Hardware Systems Design", Bell, Mudge, McNamara.
(It's a beautiful hardcover to own, but there's a link to an online HTML
on your restoration efforts! I wish I could see what all you guys have
been and are up to! Take care my friends.
