My multi-bingo has come along well - up to 8 completed games, and another two in progress.  Many thanks to Dennis Dodel, Chris Dade and Bingo Butch and his son Mike!   Next episode I should have the first hardware episode.   This episode's game is 1965's Bally 50/50.  Bally has made an interesting, low-production 2 player game here - 1/2 of the playfield is essentially not useful for scoring or progression at any given time. http://ipdb.org/showpic.pl?id=842&picno=9964
