Found this the other day and I believe it's some sort of dev or diagnostics hardware for the original Gameboy. Does anyone know anything about this?

Minolta uses this box, a Nintendo Game Boy and a special jig to fix their cameras。I am very interested in its internal circuit, can you provide detailed photos of the front and back of the board? thx

Thanks for your photos! According to the photo, I will organize the circuit diagram. But you will find some resistors have no value (because I can't see the color ring on it), FETs have no model number, and some wires are broken (because they are hidden under the IC and socket). I will keep working on it. Thanks again for your help!
