If it's only got 18 pins (per the subject line) then I don't think it
can be a 27S29. Based on the label my guess would have been a PAL/GAL
of some kind, but I can't immediately think of any standard parts that
would have had less than 20 pins there either...

Thanks Bob- this is alongside the 27S29 parts- which are labeled as such,
but this question is about a part labeled AM76 (different than the
27S29 which are clearly labeled).
Are you saying they're identical?

has a few of these ceramic DIPs with the same Apollo P/N labels as the
Am27S29 and similar programmable parts.
