 Don't know if it's similar to what you've seen or not, but from my
 experience testing M-series modules for the -8/L and -8/i, I've found
 more dead 7474s and 7440s than any other type of chip. 
That is what we found from our recent PDP-8/L revival.
We also found quite a few failed 7400, 7410, 7450/7460,

I bought a HP 10529A Logic Comparator that sounds like the chip test
device that you made.
