KD11-E CPU
The KD11-E CPU was the first CPU version for the PDP-11/34; it consisted of two hex printed circuit boards, the M7265 Data Paths module and the M7266 Control module. They plugged into a modified MUD backplane, the DD11-P backplane, which was customized for the KD11-E.
Although it supported the KY11-LB Programmer's Console, including the diagnostic functionality which allow the CPU's microcode to be single-stepped, it did not support the FP11-A floating point unit or the KK11-A cache; a PDP-11/34 system needed the upgraded KD11-EA CPU for that.
KY11-LB Interface
The microcode diagnostic interface to the KY11-LB is carried over two 10-wire flat cables with female Berg connectors connected to wire-wrap pin groups (denominated J1 and J2) in the upper left corner of the M7266 module. (The main functionality of the KY11-B is done over the UNIBUS, and a pair of backplane lines.)
