appear to have a seven digit part number instead of a
regular 74xxx
stamp. Is there a translation guide between this seven digit number and
regular 74xxx numbers? Most of the 74xxx parts on the board also have
these seven digit numbers.
Years ago (1978), I picked up a chip cross reference print from
Honeywell Surplus in Phoenix AZ. Looks like the numbers just might cross
correctly for you. The list can be downloaded from my archive at:

Enjoy!
