In the 1980s there was also LEGO/LOGO, a programmable interface to a line of Technic products, plus an expansion card and breakout box for the Apple II to wire it all up.

There were motors, lights, and sensors you could program. One project I remember was build a car with a light sensor on the front, and then write a control loop that uses the sensor to make the car follow a line on the floor.

Here’s a blog post about someone exploring the tech:

That looks like a lot of fun. The green display of the Apple II brings back memories. Looking at the pictures of LEGO parts and electronics, I see that the spirit lives on this day - as I turn my head to my box of ESP32s, Raspberry Pi, and various microcontrollers, sensors, relays. It makes me realize the continuity of history, and how I've managed to play from childhood until now.
