Game historian Liam Robertson has posted a video showing the rarest accessory for the Game Boy console. The owners of the rare book could use different tools like a printer, camera and TV tuner, but the keyboard never went on sale.
This is the WorkBoy that Nintendo was showing at the Consumer Electronics Show. A QWERTY keyboard could be connected to the console to be able to enter various data. All this was saved on a special cartridge.
WorkBoy was developed by a third-party company. As a result, for financial reasons, the keyboard was not released – it was more expensive than the Game Boy itself.
