Have you ever owned a console that wasn't from Nintendo/Sega/Sony/MS (and if so, what was it and how was it?)

Commodore, if they count. They kind of sat in the space between gaming platform and PC. But unlike PC/Mac, I'd arguie they were more gaming machines with computer application abilities, rather than computer application machines with gaming abilities.

I also owned something called the Gizmodo, it sat on a shelf until the company vanished. I don't know what happened to it, I was moving around a lot in that time of my life. I think it got misplaced or stolen. Or I gave it away.
