You are right DON. I couldn't believe I found a use for my outdated Bio RYTHM calculator that became obsolete on Jan 1 2000. Twenty years ago when I bought the Casio Biolator, it said on the back only good for program dates for 1901 - 1999.
The Club Bingo that matches the dates was on LA Hwy 91 and closed in 1952 per The Chip Rack.
