Real simple one but lacking data...
I have a Dataram DR-118A 16KWx12bit core for PDP-8 omnibus.
what I need is the setup to configure it as the first 16k
in the system. This way my PDP-8f will have 24k of operating
core.
The points for this on the board are P1 and TB1, I think.

There is a plastic 16 pin DIP box on the top circuit board, in
the middle of the board near the bottom. It is socketed. If you
are careful, you cal remove the top of the box without pulling
the entire thing out of the socket. This will reveal the 4
jumper wires you need to move in order to configure it.
If I recall correctly, the 8 pins on the left correspond to
the 8 possible 4K memory fields, and the middle 4 pins on the
right correspond to the actual memory fields on the DR-118.
