Minolta HIT System: Game Boy Service Diagnostic Cartridges

This is something that I’ve been sitting on for a long time. The Minolta HIT system was a diagnostic tool set used by authorized Konica-Minolta technicians. They could configure and calibrate cameras using a Nintendo Gameboy. Each camera has its own corresponding cartridge. The Gameboy connects to a modified DMG-07 Four Player Adapter and then to the camera with a jig. A bit of research shows a few of these carts floating around. Here are 19 of them. I’m working on a video for our YouTube channel (https://www.youtube.com/billrogerscamera) about this system. I will be hooking it up to various cameras to show it in operation. The two service manual photos are from the Maxxum/Dynax 7 and x00si series. The cartridges share some resemblance to prototype carts. Definitely more research is required, but this was a great chance to show off my IPS modded gameboy pocket.
