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

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?
