Video game historian and Nintendo Life contributor Liam Robertson has uncovered the long-lost peripheral and unreleased device known as the WorkBoy. The WorkBoy - for those that don't know - was an add-on for the Game Boy that turned Nintendo's famous handheld device into a PDA - essentially a small personal computer.

Robertson has gone above and beyond to share the story of the WorkBoy and his own experiences with it. A trademark for this peripheral was first registered in 1992. It was designed by Source Research and Development in the UK, while a start-up company called Fabtek in the US planned to produce it in close collaboration with Nintendo.
