Anyone who has worked on a Bally Bingo machine will know that they can be a little overwhelming, to say the least.
I found this site recently while searching for some info on these machines -
http://www.bingorepair.com/.
I have only downloaded 6 out of the 11 titles available, but so far have found the info to be very useful and well presented. Already learned a couple of things I didn't know. Good information on some of the critical switch adjustments on these machines.
Now looking forward to getting back into my bingo machine.
