    Quoted from Mathazar:

    Got my display tester board the other day - thanx very much, gianfri. I had a chance to play with it tonight and it's going to be very useful to me. Nice product.

    On your video it mentions the driver or level shifter transistors as likely suspect when a digit fails. FWIW in working on hundreds (maybe thousands?) of these display boards about 90% of the time it's the 300k Ohm resistor opening up. Just letting anyone reading this know there are a couple of known causes when a digit fails on these early Bally and Stern displays.
