I don't disagree. I was speaking of the LINC-8, which was a very different
machine inside - it really was an 8 _and_ a LINC in a single box. The front
console actually had a complete PDP-8 console _and_ a complete LINC console,
side by side - two sets of lights, two sets of switches, etc.

Nope. Check out the manual I cited. Well, the LINC-8 and -12 might be similar
(almost identical, probably) from the _programming_ point of view, but the
hardware was organized totally differently (above).
