Well, I've looked in my two Texas Instruments TTL data books (1979
and 1989 versions) and neither of them list the 7429. Are you sure
it's a TTL 74-series part? Because "7429" is also a valid date code,
indicating 1974, week 29. Is there any alphabetic prefix or
suffix on the number, like SN7429? Are there any other numbers
on the chips?
