Calculators Help Identifying this old calculator EACA P-1104A

  1. Oct 17, 2012 #1
    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.
