Hi I'm restoring a PDP-8/a with the help of some friends. The CPU is now passing the MAINDECs I've thrown at it. The memory is a modern semiconductor board my friend Anders Sandahl made.
This machine is pieced together from several others and the limited function panel I got does not match the backplane I have. My theory is the DEC simplified the design of the boardto cut costs and simpler design is not compatible. Mine is labeled (on the PCB): "LIMITED FUNCTION BD. 5411507 5011506C-P2" And the one I need is: "LIMITED FUNCTION 5411165 5011167" However, the picture I have of the other is not so good. I may have read the numbera wrong. I would very much like to buy one to finish this project. /P
