Abstract

A bowling score computer system having manual input of pinfall data via thumb-wheel switches. The switches are sequentially scanned to derive data for use by a solid-state electronic computer to derive individual and team scores. At regular periodical intervals, the switches are rescanned to derive up-todate output values in case the output should be changed. The system has the capability of operating in a handicap mode or in a scratch mode. The input switches serve as an input storage memory and eliminate the need for most other internal memory within the system.
