Hi -
I have a PDP 11/40 (details below). Does anyone have an octal program listing for the diagnostic console bootstrap program, so that I can manually toggle in and use to interact with the system using a DEC Writer LA36? At the moment the M9312 ROM card is not working correctly, or it's putting the bootstrap in the wrong place and I can't find it. In the meantime If I had a listing of the bootstrap program I could manually toggle in the bootstrap and test the serial card ( M7856 )/use terminal for input. The system holds and returns memory just fine. Here is a video:
