Have the chips in your M9312 and:

Load and Examine 773000, 773200, 773400 and 773600 (for each Prom address):

The first three digits:
040=A
041=C
042=D
...
046=M
..
050=P

The final 7 bits are ASCII:

ex.,

60=0
...
111=I
112=J
113=K
114=l
...
124=T
etc.

Ex: 042114=DL

You should be able to ID any M9312 PROM in this fashion.
