I wanted, but could not find a cleanly formatted list of the PDP-8 Omnibus signals.
So I've created the list below from Appendix B of the "PDP-8/e/f/m MAINTENANCE MANUAL VOLUME 1"
Please let me know if:
- Such a list already exists
- This list is of any use at all
- There is a mistake in my list
- (almost certainly) References to M830, M835 & M836 should be M8300, M8350 & M8360?
- You know of any (other) errors in the appendix data
- Any other information should be incorporated in this list (and where to get it)
eg: Type/Class of signal (power, bus, ctrl, misc, etc)
- Other formats for this list are of any value? (eg: CSV)
Notes:
- I'm not very familiar with the signal names, some of the those found in the appendix may not be the definitive ones
eg: those given for C1L, C1V seem weird
- This list is created by some manual editing of a source list, which is read by a program to produce the output below.
So simple formatting changes are easy to make.
- OCR errors are possible, but I think I've caught them all
Some changes were made to the values found in the appendix:-
- '-' replaces spaces in signal names
- P.S. replaced with PSU
