From: Sherman Foy 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). Noel
