Hi Dan
The power connector you need is the 12 pin one at the center.
I was wrong about the 44 pins. The 44 pin ones are for expansion.
Here is a list of the connectors:

The RAM sockets can be filled with 2114's. I think Jameco still
has these. The RS-232 will drive +5 to 0 if the other end will
take it, otherwise, you'll need a -12V connected to the -VN pins.
You then change the jumper GG to 40.
Data for the basic ROM's and parts of manual can be had at:

If you need other things, let me know.
