Nintendo Game Boy Color Prototype hardware CGB-STB-X2
This is a prototype board for the Nintendo Game Boy Color. This is
the type of board that would be sent to game developers to test their
game code before Nintendo had the production units ready. If you look
closely you will see it has all the parts of a Game Boy: Starting
at the upper-left and going clock-wise you will see the two LED-looking
IR transmitter/receiver. Then the large cartridge port, little white
plug (forgot), GB Link connector. Down the side is the volume control
(the big round thing is the speaker) and then the headphone jack.
The big grey thing is the power port (it uses a SNES power supply).
On the other side- the red circles are the controls, and of course
the LCD display directly above them.
Back of the board (which
is fairly un-eventful):

the unit running a game (taken by the person that sold me the board):
