While trying to dump the truth table of all the known revision of MAD address decoder IC (with no$cash assistance), I had to figure out the pin-out of the MAD-2 chip since that information didn't seem to be available online. Here are my results (with no$cash signal name correction) for those of you who are curious or need the information for one of their project.

 mad2pinout

 

And here is the truth table:
