    Fixing the Coleco Gemini I was given. :)
    Close up of the CPU for a friend.
    Close up of the CPU ...    		 Annnnd IT WORKS! :D ~0.5 hours of toying around & ~0.5 hours of letting my iron warm up :) Ahhh, classic gaming at it's finest... As a side note, "Venture" is a really cool game.
    Annnnd IT WORKS! :D...    		 Sooo, after noticing the left direction didn't work on the player 1 port, and the player 2 port didn't work at all... I re-soldered all the pins on the ports, and fired up two-player Ice Hockey to test!

    After re-soldering the power jack (which was wayyyy more annoying that it should have been), I tested it out... It works! ... Sort of... Can't use the right direction on the first player port and the second player port doesn't even work.

So, I'm missing a few pictures; but basically: The fuse from the burnt PSU was the same as the one in the Proxima, and after a bit of soldering on the Proxima and some hot glue (to prevent more burning on it's board) it was back up and running! I saved my company like $1000.
    So, I'm missing a fe...
