PDP 11 minicomputers

There is great support for programming PDP-11 machines from ITS. Software tools are:

• PALX - assembler.
• 11STNK - linker.
• 11SIM - simulator.
• STUFF - write to PDP-11 memory.
• And plethora of DDT-like debuggers, most named RUG.

On the hardware side, there is the "Rubin 10-11 Interface" made by Jack Rubin. It's a device which is mapped into PDP-10 memory space on one side, and eight Unibuses on the other. Here's a list of the attached processors:

• TV-11, the Knight TV controller; a PDP-11/20. See Managing the TV‐11.
• XGP-11, for the printer; a PDP-11/10. See The XGP Printer.
• CONS, Lisp machine prototype. Also GT40 as its console.
• CHEOPS, chess accelerator.
• Logo group PDP-11/45. See SITS.
• Micro automation PDP-11/40.
• Vision PDP-11/40.
• CHAOS-11, Chaosnet gateway for the AI PDP-10.

Some other PDP-11s on the MIT campus:

• Ed Fredkin's GT44 / PDP-11/40.
• The Plasma Physics Grinnel TV system attached to MIT-MC.
• The MIT-MC front end PDP-11/40 with custom software.
• The MIT-MC DC76 front end with custom software.
