ABSTRACT:
An electronic tabulator for computing and displaying running totals of six different cells as well as a running total of the combined cell count. Means are also provided for dividing the individual cell count by the total cell count to express the individual cell counts as a percentage of the total. In a preferred embodiment, a keyboard provides data entry to seven commercially available calculator chips which compute the running totals and individual percentages as well as provide an output to individual LED displays.
