The '''KB11-D''' [[Central Processing Unit|CPU]] is the later CPU for the [[PDP-11/45]]. The optional [[FP11-C Floating-Point Processor]] and [[KT11-C Memory Management Unit]] of the PDP-11/45 plugged into the CPU's [[backplane]].

In addition to [[main memory]] on the [[UNIBUS]], the KB11-A could also use high-speed [[Metal Oxide Semiconductor|MOS]] or [[bipolar]] memory, specific to the PDP-11/45, which plugged into a special [[bus]], the Fastbus, which was also part of the CPU's backplane.

==Boards==

The KB11-D board set included many of the same boards as the [[KB11-A CPU]]:

* M8100 Data and Address Paths
* M8101 General Register and Control
* M8104 Processor Data and UNIBUS Registers
* M8105 Timing and Miscellaneous Control
* M8109 Timing Generator

with the following differences:

* The M8102 Instruction Register and Decode was replaced with the M8132
* The M8103 ROM and ROM Control was replaced with the M8123
* The M8106 UNIBUS and Console Control was replaced with the M8119

In addition, the CPU includes either:

* M8116 Segmentation Jumper Board

used when the KT11-C Memory Management Unit (termed the KT11-CD in this CPU) is not present, or:

* M8107 Segmentation Address Paths
* M8108-YA Segmentation Status Registers

which comprise the KT11-CD (the M8108 Segmentation Status Registers board of the KT11-C was replaced with the M8108-YA variant).
