I was looking around my box of old boards and
found a core memory set I've had since about
'84. It was a leftover from an old system
that had been surplussed. I think the system
was a PDP-8 of some sort, but I don't know for
sure. The memory set consists of a SENSE board
and an INHIBIT board connected to the sandwich
layer of five board containing th core. There
is a label with the following:
EM electronic memories
a division of electronic memories & magnetics corporation
4KX12 CORE MEMORY STACK
270321 47071MW
P/N 906819-A04 S/N xxxxx
C/N TS906819A D/C 5272
There is an actual serial number, but the first
digit is torn.
The plastic strain relief strips and the card edge
handles both have "DIGITAL EQUIPMENT CORPORATION"
and "MAYNARD, MASSACHUSETTS" on them. The handles
also has "W025" on them.
Is this a PDP-8 board, and was it an OEM part
supplied to DEC or from DEC?
