The Rally Home T.V. Game system is one of the earliest release by Videomaster, after the Home T.V. Game of 1974. No central line, no on-screen scoring, no sound effects.
Service is manual and scores are kept using small plastic cursors on the system itself.
Some other systems offer the same games. The Orelec PP-2000 is the best example, but this system does not have the plastic cursors for the manual scoring. Top cover of the user manual. Instructions to play four games.
