- In this video I look at a retro video game I built using a chip commonly used in the first generation video games of the early 1970s.

I never knew that all these machines were based around a few common chips. I'm super excited to see what the additional colour chip does! Thanks for sharing.
So great to see this. In what must have been very early 80's with me just a tad over 10 years, I tried to build one from an article in a Portuguese electronics magazine called "Seleções de Rádio". Remember going with my father to get the AY-3-8500 and being told to return as it needed to be ordered. Also, did the PCB hand-drawing and etching myself. Did assemble most if not all of it, but don't think I ever took this to total conclusion. Eventually got interested in micro computers, so a few projects like this one just got left hanging.
My first video console back in the 70s was a Coleco Telstar, which looks like it used that chip. With so many different consoles out there with basically the same gameplay it must have been a struggle to get noticed and get market share unless you were an already established company. Thanks for showing your project!
In the 04-05/1982 issue of the "Radioelektronik" magazine there was an article describing the construction of a video game based on AY-3-38610. I also remember the article about the motocross game with AY-3-8765.
When I was a kid, I had a TAB book, "The Giant Handbook of Computer Projects" that described this chip. Or maybe one similar to it, as I think it supported a light-gun game too. Anyway, this was the early 90s, and I'd gotten this book out of a free bin at a used book store. It seemed so cool, like I could build my own video game!!!!! Right? So I asked all around at all the radio shacks and computer stores, trying to find one of these chips, but everyone thought I was crazy, and I never did find one. Lol.
Very nice project, thanks Jeff
Great fun - it's the sounds that really invoke nostalgia for me. We had a slightly later model that supported PAL colour and the rifle games. Interesting that the colour units still used the AY-3-8500, with the colour implemented externally (presumably on the AY-3-8515).
I still have my first home made TV game, which used the AY-3-8550 instead. This was the later version of the AY-3-8500 that used potentiometer joysticks for full X/Y movement of the bats, which made the games a whole level up in fun / skill possibilities. You're inspiring me to maybe make an updated PCB for my AY-3-8550, dropping the onboard RF modulator as you've done etc.
Thank you . I have a similar one and I thought it not working because the ball passes through the paddles ...
Now I have read that it happens if you speed the paddle too fast !
I've made a little PCB that creates an RGB output for the AY-3-8500-1. It probably will work on the NTSC version as well. If you like I can send a schematic to you.
I'd like to see a decap of the chip.
The AY-3-8500 was used in the ELWRO TVG10 console produced in Poland.
