Supercoder 2000 Keyboard is designed for nerds

I’m not a computer geek by any means and this Supercoder 2000 Keyboard is designed for. That’s why the purpose is sort of lost on me. It only has 3 keys which are a zero, a one, and a done button. I think to a layman like me, this seems completely useless. It also has a cooling function. Anyway, if any of you know how to use it, let me know. I’m quite curious. This a keyboard with the least number of keys I’ve ever seen. It’s a binary keyboard.
