The module utilization for the main CPU backplane is: slot module 1 A-B M7090 KD11-Z CIM Console Interface Module 1 C-F M7091 KE44-A CIS (Commercial Instruction Set) option 2 A-F M7092 KE44-A CIS (Commercial Instruction Set) option 3 A-F M7093 FP11-F Floating Point option 4 A-F M7094 KD11-Z CPU Data Path 5 A-F M7095 KD11-Z CPU Control 6 A-F M7096 KD11-Z CPU MFM Multi Function Module 7 A-F M7097 KD11-Z CPU Cache 8 A-F M7098 KD11-Z UBI Unibus Interface 9-12 A-F M8722 MS11-M memory (256 KB ECC) or M???? 1 MB ECC 13 A-F SPC (quad or hex), 13 A-B are MUD 14 A-B Unibus terminator or output 14 C-F SPC (quad) Note that slot 1 is the rightmost as the machine is viewed from the front, and that row A is toward the read and row B toward the front. If you install or remove NPG devices in slot 13 or 14, you may have to wire wrap some lines on the backplane. Unused SPC slots require a G727, G7270, or G7273 card for bus grant continuity.
