A December 1956 cover feature article in Radio-Electronics magazine describes "Relay Moe" which plays tic tac toe with adjustable levels of skill. It used 90 relays.
This is a subject dear to my heart. I'm a mathematician who routinely uses symmetry in counting problems. As a kid I remember writing out a tic tac toe game tree in about ten pages. I must have used symmetry, and I must have only mapped a winning strategy, not all 765 game states up to symmetry.
So my first reaction to now reading that Bertie the Brain used "addition tubes" was "Really? Can't you do that with relays?" And the reality is that Bertie the Brain was a solution looking for a problem, a demo project for these tubes, not an attempt at the simplest way to implement such a machine.
Still, looking at the numbers, I'm impressed that Relay Moe managed multiple levels of game play using only 90 relays. The design exploited symmetry.
The article says this was for the 1950 Canadian National Exhibition, and it appears that a high-schooler Donald Knuth got to see one such machine in Chicago (possibly on a school trip; he grew up in Milwaukee) long before his first encounter with a computer, as documented in TAOCP vol 4A:
> This setup is based on an exhibit from the early 1950s at the Museum of Science and Industry in Chicago, where the author was first introduced to the magic of switching circuits. The machine in Chicago, designed by researchers at Bell Telephone Laboratories, allowed me to go first; yet I soon discovered there was no way to defeat it. Therefore I decided to move as stupidly as possible, hoping that the designers had not anticipated such bizarre behavior. In fact I allowed the machine to reach a position where it had two winning moves; and it seized both of them! Moving twice is of course a flagrant violation of the rules, so I had won a moral victory even though the machine had announced that I had lost.
Later, a program for playing tic-tac-toe was one of the first programs he wrote, after he entered college and discovered computers. (He also quotes Charles Babbage! https://research.swtch.com/tictactoe)
As I was reading through this, I came to the part that mentions the cathode-ray tube amusement device and the words instantly unlocked a long forgotten memory I had as a child reading DK illustrated books on science and tech (I can't recall what the book was called) and it's where I learnt about it being the first video game ever.
Only tangentially related to this article but it took me back!
> “If the solid-state revolution had started ten years later, I would have been a billionaire,” he says. “Everybody would have used Additrons instead of these big circuits.”
I feel like this is the sentiment on HN for so many startup projects that seem adjacent to other innovations
I miss the days when video games were used to showcase technical advances.
"Kates built the game to showcase his additron tube, a miniature version of the vacuum tube, though the transistor overtook it in computer development shortly thereafter."
They sort of still are (Witcher 4 being used to showcase new UE features and software+hardware optimizations is just one example), but we're getting close to the point where we cannot really add more details and realism to video games and they still don't really hammer the hardware. Seems ML is the new showcase if anything :)

Lots of human senses aren't tackled by video games yet. Smell, taste, balance, cardioception, proprioception, pain, temperature, pressure are all missing. Where are the immersive tanks or piezzoelectric coveralls that stimulate all of our senses coherently? I bet adding those would hammer the hardware.
SF author Fred Saberhagen used an "automated" tic-tac-toe in one of the first Berserker (intelligent machines bent on wiping out organic life) stories.
The protagonist was a scout spaceship pilot, who for plot reasons had to simulate being alert in communication with a Berserker that could kill him if it determined he wasn't.
If memory serves, he devised some sort of branch elimination algorithm using matchsticks, so that his tic-tac-toe games improved with iteration...

Additron not addition.

On the tic tac toe topic, MENACE is just startlingly cool:

Man Canada used to be so impressive. We need to get back there
RIP Avro Arrow
So ... Joshua was the next evolution of Bertie?

That was 1963: https://en.wikipedia.org/wiki/Berserker_(novel_series)
Toronto leading AI since the 50s woo!
the mechanical chess computer was even more impressive imho
https://en.wikipedia.org/wiki/El_Ajedrecista
early 1900s, that's incredible
the first electronic computer playing chess was almost 50 years away
Note that it only played a single endgame scenario consisting of three pieces.
Still more difficult than Tic-Tac-Toe...
Granted.
What, no small-statured chess mastermind hidden in there? :D
