Sweet. This summer I may be building one, depending on when I get this hip surgery and recover.

Good Luck to you with your hip and a rack build. Helpful Tip... The best thing that I did was to put wheels on the bases. It makes life so much easier when you need to add, remove, or connect anything.

And the highlight to me is the Predicta TV's. Do they work?

The answer is really no. But the Predictas do light up, but due to internal component degradation over the years, you really want to unplug them asap.

Wow! 13 digit.

Did you know that, before this was a game, it was a calculator?

8-digit, with 8 registers.

This was the counting board. And it is why the desk with the cash register is called a counter. It was carved into one end of the counter.

A special marker (not part of a checker set) placed the decimal point. I know how to add, subtract, multiply, divide, and extract square roots on one.

The game appeared when clerks with nothing to do played checkers.

Link? I must find out how to calculate a square root using a checker board!

Well that's mostly true as I can find no reference to the game of checkers. However grids were used with counters for calculations.
I confess I did have to google this one, and not to rain on your explanation but out of curiosity.
