My lifetime, specifically.
For purposes of completion, the Game Gear came with an NHL All-Star Hockey cartridge.
I haven't yet tested the Colecovision steering wheel or the Pac-Man tabletop game, as I don't have the right size batteries. Everything else has been tested, and the verdict is in: The Game Boy Color, the cruddy Colecovision and two SNES controllers do not work. All the remaining stuff works!
The Fairchild Channel F plays Pong OK and the controllers work, but the Hockey option doesn't seem to play. I don't have a cartridge to try on it.
The Master System works except for the "reset" button. Whatever. I don't know if the 3-D adapter works, because I don't have the glasses.
The crown jewel is a very nice Colecovision. The controllers are in great shape, as well. I am really happy with this console, because I was Craigslist scammed on my first one: The guy met me in a parking lot to trade me his "working great" Colecovision for my N64. Needless to say, his console wasn't working great.

Thankfully, shortly thereafter, I was able to get another N64 for just a few bucks.
Some of this stuff will eventually be for sale.
