Nintendo Gamboy Demo Vision Development Unit

The Nintendo Demo Vision is a development and kiosk device which uses NES hardware. The Gameboys are hardwired to receive power and to send their audio / video data to the main unit. Games are still inserted into the systems, with the image and sound simultaneously sent to Gameboy screen and speaker as well as the Demo Vision’s A/V outputs.

The one handheld Demo Vision`s were used in the Gameboy Display Kiosks, while the two system units were apparently for development purposes. Inside are NES motherboards, each with individual RF and composite AV outputs. Each has EPROMs for PRG and CHR data with an on-board MMC5 mapper.

I don`t think I`ve seen one of these for sale since 2008, and that one has no systems.
