    Please help! I'm looking for info about the very first Electronic calculater I ever saw. The time was early 1960'es and the "thing" was about the sizeof a modern Cash register - it had what was called "a full keyboard" whichmeans its keyboard in addition to signs for add. sub. div. and mult. had numberkeys in a 9 x9 layaout. I think ist brand name was Sumlotronic, but I have not been able to find any information about it anywhere.

    ** Err - did you think of trying Wiki ?

    http://en.wikipedia.org/wiki/Calculator#Development_of_electronic_calculators

    The para describes the Sumlock ANITA made by British firm Bell Punch.

  4. The ANITA has its own page:

    Fantstic thing.
    It took them years to get rid of the 9x9 keyboard!
    That's INERTIA !
