    Calculator
In summary, a user is seeking help in identifying a calculator from the 70's or 80's that has been modified and has no identifying marks except for a circuit board part number. The calculator features keys for "S.T." and "A.T." which could potentially stand for "subtract from total" or "add to total". The user is hoping for assistance in determining the purpose of these keys.

Hey guys,

New to the board, hoping someone can help me.

I am trying to identify what I believe to be the face of a very old calculator, circa 70's or 80's. Unfortunately it was butchered by someone for a project and there's no identifying marks, except for a part number on a circuit board on the back - EACA P-1104A.

If anyone can help, it would be appreciated. It looks like it had some sort of speaker and I've never seen keys for "S.T." or "A.T." on a calculator before.

Don't know the calculator, but the "T" probably returns a value from "T", AT may be add to "T" or add "T", ST could be subtact from "T" or store into "T". "T" is probably some form of a total. CE os clear entry.
