Bally bingos are very different beasts and would be the most difficult EM to repair of the era. VERY HEAVY - and it is all "head". My old man used to call these machines "The original computer". I have paperwork on some 50's Bingos, but no 70's Bingos. Even have some NOS Stepper units in storage.
Let me know if you need anything Daniel and good luck
