Accounting Log
The following is from a paper cocktail napkin found in a Bally Bikini - who says the operators didn't keep good records!
The meters in this game were wired to record the number of coins deposited and the number of coins payed out (reset from the replay register by power cycling the game). Note that this is different than the number of games played and the number of credits won. In slot machine terms, it's the amount people cashed out....and we all know that most people keep playing until there are no credits left.
The year is unknown. If you aren't used to casino terms, Hold is the the money that you took in, minus the money you paid out.
Assuming the operator split the income with the bartender, this machine pretty much paid for itself in the 9 months recorded on the napkin. A strong location could do 4 times more volume - or more.
This game operated on nickles.
