PDP-6 questions

Seth asks: I don't know about the BCM, but I have a couple of boards from decomissioned PDP-6's. They were not disassembled out of malice but out of lack of facility to store them. In between scraps found on the DECUS sources and some files I've cobbled together over the years from friends in the southern hemisphere, I think I have two mostly complete sets of sources for the PDP-6 monitor. I discussed this a bit on alt.sys.pdp10 last year. Get me worked up and I might actually get them to build :-). Right now they're at http://pdp-6.trailing-edge.com/ Note that most of the early DECUS LIB-10 entries are actually PDP-6 software (with occasional notes on what you have to patch/modify to make it work on a -10). I highly recommend that you browse them. Last year on alt.sys.pdp10 I also initiated some discussions about the MACRO differences necessary to assemble the earliest source files (where the syntax was slightly different). I have mentioned to Al that I am very interested in the oldest 36-bit Macro source files that he has from the LCG archives. I suspect there's at least some interesting stuff there but it's hard to sort out. Tim.
