DEC PDP-11/35

S/N DR07235

This PDP 11/35 was donated to the RICM by Quickware Engineering & Design, Inc. The processor is complete but does not have the optional EIS, FIS, stack limit, and MMU boards. The memory backplane is not in the chassis and was probably core. This is a real blinkenlight machine with a full switch panel and lights.

It is mostly empty because the core memory backplane did not come with the system.
We added a 4-slot backplane and installed a 16-KWord 18-bit RAM board.
