|Arcade system(s)||Discrete Logic|
According to Discrete Logistics, Exidy TV Pinball has a licensed version called TV Pingame by Chicago Coin. Flipper Ball by Cinematronics, Knockout by Ramtek, TV Flipper by Midway, Pinball by Diversified Entertainment, and Ricochet (Nutting Associates) also appear to be the same game. It is not known what the first game was, but it appears to be Knockout.
The Dumping Union's got one.
The theory was, this was a (prototype?) production discrete logic game that was (not?) released by Ramtek and instead went over to Exidy after the Ramtek split, where it was renamed TV Pinball. Exidy also acquired Table Football / Table Foosballer in this manner. However, the TV Pinball schematics are not a match.
ASSY # 550300. (If going in ASSY# order, in theory Knockout should have been released between 06/1975 and 11/1975? Maybe 09/1975?)
