I was wondering when Bally went to a solid state version(s) of their bingo's?

Thanks for the info folks. The last time I played on a bingo game was 1966!!!!
I am looking to buy a machine some time soon. I had a chance to get a Hawaii.
But I had never seen a 20 hole game. I understood that the Hawaii, Mystic Gate &
Double Up were among the last machines before the solid state units.
Back in the day the only machines I saw were 25 holer's.

I'm hoping to pick up a 25 hole Bingo soon.
But, here in eastern Canada; New Brunswick, Nova Scotia, I am finding it
almost impossible to find any Bally bingo's at all!!!!
There has to be some around, I just can't find them.YET!

Thank you BingoButch for the info!
I will look this guy up for sure.
BTW I have a line on a guy in Toronto who has 50 to 60 Bingo's.
Any one want me to forward list, you can PM me.
Toronto is over 1000 miles from me; just a bit far!!!

I was off on the number of bingo's the guy in Toronto has.
It is 37. He also has quite a few Back Glasses.
Some new, according to him.
There is supposed to be a guy in Halifax with quite a few Bally bingo's.
If there is any one out there that has a line on this could you please PM me.
Thanks,
Terry K
