How about the IMP-16 CROMs? Again, I think it takes a

to read those.

The "generic" part number for an IMP CROM is MM4751 or MM5751, with the
4 vs. 5 designating military vs. commercial, respectively, and with a D,
J, or N suffix designating glass/metal DIP, ceramic DIP, or plastic DIP,
respectively. They rarely had the MMx571 part number stamped on the
package, though. I think I've seen that exactly once.
The actual part numbers (sans the D/J/N package suffix) are:
Military Commercial Description
----------- ----------- -------------------------------------
IMP-8A/420 IMP-8A/520 IMP-8 CROM
IMP-16A/421 IMP-16A/521 IMP-16 basic instruction set CROM
IMP-16A/422 IMP-16A/522 IMP-16 extended instruction set CROM
IMP-16A/423 IMP-16A/523 IMP-16 POWER I/O CROM
IMP-16A/424 IMP-16A/524 IMP-16 Arithmetic CROM
I don't have any definitive reference for the part number of the IMP-4 CROM.
