Here’s one that you’ve probably never heard of before. Featured in Volume 36 (May 1992) of Nintendo Power Magazine, this is the “Work Boy”.
The Work Boy turns your original Gameboy into a little work station by loading a personal diary, address book, clock, calendar, and more. It has the ability to be plugged into a keyboard for easy data entry. Pretty ambitious for the time. Probably due to low interest, the Work Boy never actually saw a release and only the one in the picture and perhaps a few other prototypes yet to be found in some developer’s desk somewhere were ever made.
