I'm working on my pdp11/10 getting it back

problem I think I have is that the secondary memory (a

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.
