Make-It-Yourself projects TV Tennis (Elektor, 1975/76)

This project was originally published in the 7th issue of Elektor in november 1975 and featured a Tennis game in its simplest form: two paddles and a ball. The design used 13 TTL chips (74xx series) in analog mode. Later in 1976, Elektor published several improvements in issues 11 and 13: new games, the central line, top and bottom boundaries, sound effects, automatic scoring, and also a "solo" mode where the second player never looses by staying at the same vertical position than the ball. Other changes improved the picture quality.
