PDP-12 at the RICM

[Kip Koon]

Hi Michael,
I would be most interested in finding out more about this effort.  Do you have ongoing pictures documenting this effort?  I'd love to have a PDP 8, 11, 12 someday, but I don't have the space for something like that much less the cost involved so I'll have to be satisfied with emulators on my PC or eventually building one or more of these systems with current technology like the SBC6120 if memory serves.  Are there other possible alternatives?  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?  Congratulations on your restoration efforts!  I wish I could see what all you guys have been and are up to!  Take care my friends.
