I still have mine in the closet. I learned to code in TI BASIC on that beautiful machine. I've kept it for 35 years because it's the biggest single influence from my childhood on who I am today. I should pull it out and relive some old memories.

That said, there's no way in hell that video was a TI BASIC program. There were way too many sprites moving too smoothly around the screen. They must have made a custom cartridge.
