Does anyone have an explanation of what the Unibus pins do?

Hi: I had the same question, and Tim Shoppa lent me a book that (unfortunately) only provides a technical description of the UNIBUS, specifying line names etc. This is great but the bad part is that the book does not cross reference the lines to particular pins on the backplane. I want to poke and prod the backplane with a VOM due to an unfortunate power supply blowup (read as "I goofed!") and am still going to be unable to do this. The text does "name" particular pins, but the naming system is not self-evident nor does it seem to follow a logical association with the backplane slots. Most of the pins start with A through F, but beyond that it's not possible to figure out which pin is which. If you find out, please let me know! Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca
