Emerson PS/2 Library

This is a project to interface AT and PS/2 protocol peripherals (keyboard and mouse) to the TI-83 Plus series calculator.

The electrical interface between a PC and an AT or PS/2 device is very similar to that provided by the calculator's link port, so all an adapter needs to do is provide power to the peripheral and convert the DIN socket connection to a 2.5mm mini stereo jack plug.
