If you were a child in the 1970s-1980s like me, and if you love Legos and technology, then maybe you've wondered: Wouldn't it be great to control your Lego creations (or other real-world systems) with the 8-bit computers of your youth? You can!

In the steps below, I explain which parts you need to acquire. When shopping for Lego parts, I recommend using Bricklink. There are other good choices such as BrickOwl, eBay, etc.

You'll find 99% of the manuals and software at Archive.org in the Vintage Lego Robotics collection.

Click a menu number: 0. The history of Lego 8-bit robotics. 1. Start by building the Universal Buggy. 2. Acquire and learn to use an 8-bit computer from the 1970s-1980s. 3. Acquire or build the Interface A. 4. Acquire or build the card/cable for your Apple II, BBC Micro, Commodore 64, or IBM PC. 5. Acquire lights, motors, sensors, and wires. 6. Pick your programming language or application. 7. If you want something simpler, then build an analog robot. 8. If you want something more advanced, then read about 16-bit systems and beyond.

Boycott the "Beyond the Brick" social accounts! I urge everyone to NOT visit or share their posts. It's bad enough that they download and monetize other people's videos, taking all of the views that belong to creators. But now they're consistently allowing "jokes" about death and tragedy. Specifically, they've posted several Lego builds of the New York twin towers. Every time, there are hundreds of appalling comments about airplanes. Several other people and I called them out, and the response has been silence. They have a great video with me from Brickfair, which I've removed from this website and I advise not watching. Had I known their terrible ethics, I never would have allowed them to film me. BOYCOTT THEM until they grow up and act responsibly.
