Thanks Bob- this is alongside the 27S29 parts- which are labeled as such,
but this question is about a part labeled AM000076 (different than the
27S29 which are clearly labeled).
Are you saying they're identical?

Title says all,
Backing up all the programmable parts in the Apollo DN100 and the CPU
board
has a few of these ceramic DIPs with the same
Apollo P/N labels as the
Am27S29 and similar programmable parts.
Thanks
