11/15/2017 - Silverball Mania or Six Million Dollar Man... who's your daddy?
I spent some time reconciling serial numbers which start with the 'ESM' prefix. Both Silverball Mania and Six Million Dollar Man use this same prefix so it can make game part assignments a little tougher. I found that most Bally PCB's have a datecode on them and in this particular instance I found several pics with a datecode of '11-79' or just plain '80'.... so all of those mystery ESM serial numbers were clearly Silverball Mania serials since Six Million Dollar Man was released in October of 1978.
