Hi Michael,
I would be most interested in finding out more about this effort. ... I used a
PDP-8/E in high school and college
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.

Subject: Re: PDP-12 at the RICM
The RICM Learning Lab was nice and cool today so we spent the afternoon chasing the
"LGP GP=GPC PRESET" in the TC12 LINCtape
controller. With a logic analyzer connected to lots of the TC12 signals were
were able to chase down the signal that is causing the
fault. We are now not sure if the signal behavior we observed is the correct
behavior, and there is a fault elsewhere. More debugging
time and more studying of the documentation is required.
