The copy of the KD11-EA engineering drawings (in the 11/34A Field Maintenance Print Set, MP-00190) on Bitsavers is missing most of the pages that hold the microcode flow diagrams. I have a set of the KD11-EA FMPS (MP-00192), which does have all the missing pages, which I can eventually scan. However, in the interim, the 11/34 Field Maintenance Print Set Vol. 2 (MP-00082) on Bitsavers has a complete set of microcode flow diagrams for the KD11-E (pp. 15-40 of the PDF), and they are almost identical to the KD11-EA diagrams. The only difference I can see (I compared page by page, to see if each page had the same microinstructions on it) is that on sheet 17; the last microinstruction for RTI/RTT has been moved from 002 -> 744. (The actual microinstruction contents seem to be the same.) I don't know whyo the changed address; I originally thought that perhaps they had to re-do the IR Decode ROMs when they added floating point, and they needed the original location to handle the start of the floating point microcode, but that doesn't seem to be the case.
