-The '''KD11-Z CPU''' was the [[Central Processing Unit|CPU]] of the [[PDP-11/44]]; the letter code 'Z' was a tip to the fact that it was the last native [[UNIBUS]] [[PDP-11]] CPU, and the last to be made out of discrete [[integrated circuit|chips]], and not a [[microprocessor]].
+The '''KD11-Z CPU''' was the [[Central Processing Unit|CPU]] of the [[PDP-11/44]]; the terminal letter code 'Z' was a tip to the fact that it was the last [[PDP-11]] CPU to be made out of discrete [[integrated circuit|chips]], and not a [[microprocessor]], and also nearly the last native [[UNIBUS]] CPU (except for the [[KDF11-U CPU|KDF11-U]]).
 The KD11-Z used the [[Extended UNIBUS]] for its [[bus]] to [[main memory]], allowing it to have up to 4 mega-[[byte]]s of main memory. All devices were attached to a semi-separate [[UNIBUS]] (it and the EUB shared data lines, but not address lines); [[Direct Memory Access|DMA]] devices could gain access to the memory via a [[UNIBUS map]] which connected the two, and mapped UNIBUS addresses to main memory addresses.
-Full [[PDP-11 Memory Management]] and a [[cache]] (the [[KK11-C Cache Memory|KK11-B]]) were standard on all KD11-Z's. It also supported the optional [[FP11-F Floating-Point Processor|FP11-F]] [[floating point]] (full [[FP11 floating point]]) and/or the [[KE44-A Commercial Instruction Set Processor]]; these plugged into dedicated slots in the CPU [[backplane]] (it could work with either, or both).
