It looks like Ramtek had the lead with this pinball genre and Midway, Exidy and Chicago Coins and a couple others joined in the following year. It is interesting that Ramtek uses proms and actual dip switches while the other companies used wire jumpers for settings adjustments.

It had to be arcade technicians or something along that line that may have been aware of some of the 1970s era games and mentioned them when they were talking back in mid to late 1990s just when emulation was taking place. I wonder where some of the info Jim Hernandez had put into the text list file came from.

Okay. It looks like it might only be Ramtek Knockout that uses proms and all the others are all TTL. Chicago Coin TV Pin Game is all TTL. And if they did license from Exidy's TV Pinball, then TV Pinball should be same. That leaves Midway TV Flipper and wondering if it uses proms or not.

I do believe a good portion of the dip switches will relate to score settings such as free game or bonus points etc. And maybe number of coin credits per play.
