Build Your Own Sinclair ZX81 Ad, BYTE Magazine, Volume 7, Number 9, September 1982

I wish I still had mine. 3D monster maze, 1k chess, nightgunner, gulpman.

My neighbor had a zx80. I remember playing a game on that too, but i don't remember what it was.

Me too. Luckily I had a friend who studied electrical engineering who helped me put it together.

Did you build it yourself? It looks awesome!
