I found this board cleaning out a 'junk' closet in a computer room some 10 years ago.

The board had 4 sets of 8 by 8 magnetic cores copper wired together.  The label on the board says NCR memory,buffer with an ASS’Y 095C0003849 build code.  Any info on the board we be helpful.

Thanks

I'm guessing that board was part of the PC (Program Count or Program Control) logic for the 315-100 or the 315-RMC.  I never worked on it but I remember seeing them.  The Century series continued that type of control logic design (PC counts), but the implementation was different.

Thanks for the info.  After looking more closely it is really 6 by 8 not 8 by 8.  I had to bring it to work to show some of the 'young' ones what core really was for they did not know we used the term core memory dump.

Thanks again
