Plessey's My First PDP-11

[Tore S Bekkedal]

Yay, I have a PDP-11!! Yay! Yay!!

It's a PDP-11/03, it's got a CPU, and RAM, and some interface cards. 

The backplane is a Plessey PM-F11/QU, shaped like this:

     F     E     D     C     B     A

I have connected an AT PSU to +5v and GND, though there is a +15v in. Is
this used for anything?

I have tried plugging in a QBUS debugger I got on ABCD6, I have tried
plugging in the CPU (in AB9) with the debugger. Nothing. I can't get
anything to live.

Where should I plug things?

Does anything use the +15v?

Any other voltages I need?

Thanks for the help!
