This site features one Lego part:
#70288 / 70455, "Technic Control 4.5V Interface Box with Ports"
Commonly known as Interface A

Lego produced Interface A starting in 1986. It connects 1980s 8-bit computers (or modern computers through USB-C adapters) to Lego peripherals — lights, motors, optical sensors, and touch sensors — so you can build programmable models. Lego sold Interface A exclusively through their educational division. They phased it out upon releasing a 16-bit system, Lego Control Lab ("Interface B"), in 1993. Fifty years later, a small group of hobbyists around the world keep Interface A alive.

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.
