Sharp Manager is an application for connecting some vintage Sharp pocket computers with your Windows desktop PC. It works together with an Arduino to connect the pocket computer to a USB port on your computer. With this hardware and software, Sharp Manager emulates a CE126P cassette and printer interface and a sharp Sharp CE140F floppy drive. This video demonstrates both the hardware and the software.
