I don't remember any of those allowing cartridges to play. They existed, but they couldn't really be called consoles since they just played one game. This was different. I could also be wrong.
What about the Adventurevision or Colorvision? Both were LEDish, but neither I would consider color. Both accepted cartridges.
I don't think the Adventurevision or Colorvision qualify as handhelds. I was thinking of them more as tabletops. I'm not sure of this, but IIRC the Colorvision came later than the Super Micro. Good point with the Adventurevision, however.
