I have a few of the limited function and programmers panels. I do not
recall either of them being dependent on particular backplane. I'll try to
pull a few a few later and check the part number on them.
Remember, a 54-XXXXX number can become a 70-XXXXX with the addition of a
cable or something simple.

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.

F?r du inget napp s? ritar jag upp ett kort till dig, det borde g? att
flytta ?ver brytarna fr?n det du har. Lite synd att scrappa ett
originalkort bara, men ?r man f?rsiktigt s? man inte tar s?nder det s? g?r
det ju att ?terst?lla...
