Asteroids add-on board

I was digging through my storage locker and came upon a
Asteroids board that had the switch settings for that
little add-on board that came up on here a month or so
ago. It plugs into a DIP socket at C5

               1 2 3 4 5 6 7
4 increments on
5 increments on
6 increments on
22 seconds on
45 seconds on
1.5 minutes on
3.0 minutes on

now you know as much about it as I do :-)

maybe John R remembers it. sort of sounds like a
game time limiter.
