Hi there,
Just a quicker to tell you that I successfully rebuilt the round ball generator used in the 4-player Odyssey project. Although there is no surviving hardware, I used the documentation to rebuild it, and it works amazingly well. Ralph Baer was convinced that the schematic didn't work, but I went ahead. We finally admitted that there is some very clever tricks which generate bell-shaped signals which, once combined, form a round ball.
The only drawback to this 4-hour project is that I had to salvage two spot (player) generators from one of my Odyssey units to use their original transistors, which are no longer available (I didn't try to determine modern replacements). Hence why I faked player 2 on the right because the real picture showed player 1 and the round ball only, the generator for player 2 being removed from the Odyssey unit used for testing.
