tabulator - Computer Definition
A punch card accounting machine that was used to prepare invoices, checks and "green-striped" reports as late as the 1970s. Introduced in the late 1800s, tabulators initially added amounts in the cards that were displayed on dials. Subsequent models were able to perform additional arithmetic operations as well as print the results. See Hollerith machine, punch card and continuous forms.
