Hello,

I have two National Semiconductor Memory Systems 512KB Memory Boards for a PDP-11/44. These boards came out of my PDP-11/44 in working condition. I do not have any information on how to set up the DIP switches on these boards. One of the boards is Rev level K and the other one is similar, except that it has some wire mods on it and is at Rev level J. The pair of boards will give you 1MB of memory, and will work in conjunction with the DEC MS11-Px series memory boards.
These boards came out of slots 9 and 10 in my system.

Free to a good home. Just pay for shipping/packaging.



Thanks,
Howard
