I'm working on my pdp11/10 getting it back together. One problem I think I have is that the secondary memory (a Plessy 700101-100) may be shorting the -15 line for some reason. Working on it, but does anyone have a manual or anything like that for this kind of memory board?
Check for Tantalum capacitors on the -15V. These often fail after a period of not being powered and then having power applied suddenly.
