I'm not sure this is the connector you're interested in.  This is from a
bit of documentation I found for a DEC 3000-300:

Pin Description   Pin Description 
1   +5V           11  System ok 
2   +5V           12  RTN 
3   +5V           13  RTN 
4   +5V           14  RTN 
5   +5V           15  RTN 
6   +5V           16  RTN 
7   +12V          17  RTN 
8   -12V          18  RTN 
9   POK           19  RTN 
10  spkr+         20  spkr- 

There was no diagram for the connector, just this list of signals.
