A slight simplification of the operational machine ( datapath, the part of the processor that performs operations on any data. The processor module consists of 138 chips. The book is scanned and is in the public domain. However, this particular instance had only the usual limited operator console.īook Computer Engineering: A DEC view of hardware design The PDP-11 family of machines is described in great detail. Something like a rack with a set of equipment ), through which the operator could enter simple boot programs and carry out system maintenance.

Typically, PDP 11 came with a programming console ( separate panel. The modules were connected to a common cross-board ( backplate ) with nine slots performed by wrap-up. In addition, the boards were divided according to which bus they are designed for. In the photo just below 6 groups of pins are visible. In this new version, DEC was able to fit all the processor logic on one six-pin board ( PDP used several types of boards with various form factors - six-pin, four-pin, two-pin. PDP-11/04 operator console panel appeared in the mid-seventies as the cheaper PDP-11/05 successor. Together with the PDP-11 itself was the TU60 tape station. The computer was handed over in parts, but everything was in place except for a couple of screws. We received it in the late eighties from EDKX - computer club Ericsson. This PDP 11/04 was originally owned by Ericsson. Translation of an article on the restoration of an old interesting machine.
