I got one of these for Christmas when I was 10 or 12 (1967-69), Sears sold them. It implements mechanical analogs of logic gates and other elements of digital computing and could run rudimentary programs and even games.

I struggled to get the button-led board functional - in the end I had two problems.
1. There is a problem with macs recognizing boards on the Arduino IDE and in using the workflow for OpenOCD (Open On Chip Debugger) or EDBG (Embedded Debugger). I was able to install bootloaders with the Arduino IDE, and I got people with PCs to help load bootloaders in my boards. The Arduino is unreliable in recognizing my boards, works every time on PCs. I have a 2010 Macbook Pro 13 inch with a hacked version of OS 10.15.7 Catalina (Apple block Catalina form working on older macs that are capable of running it. MacOS Catalina Patcher by DosDude1 allows older macs to run Catalina and seems to have very few compatability issues). I am working to get aan older PC that I can run linux on and plan on testing the Arduino IDE on my Raspberry Pi.

2. My board powered up but would not work. Continuity tests during build and after completion indicated hat everything was connected properly. I had to ask Josep for help. He reflowed solder on many joints in the board and it just started working. The mini usb traces are very small and he suspects this was the issue.
