SpotCheck
SpotCheck was (by modern standards) a small computer program. It was used by Cable Television Advertising businesses starting in 1987. It was a basically a prototype for our Air/Traffic Controller software, which was released in 1989.
In those days a typical small-office computer had a green screen, no mouse, a 300 baud modem, and a dot-matrix printer. Windows were things that people threw their computers through.
SpotCheck was discontinued in 1992, when the last SpotCheck licensee upgraded to Air/Traffic Controller.
