Looking for Limited Function Board

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
