Numeric Keypad IIe

This is a conversion project for the Numeric Keypad IIe, model A2M2003. This was an external keypad that connected to the Apple //e's motherboard (and as such, it lacked any kind of onboard controller).

The reference conversion setup uses the keyboard's DB15 (VGA) fixed cable connected to a DB15 wiring terminal with breakout board (this one, specifically) and wired to an Arduino Micro.

Keyboard Maintainer: Adam Newbold
Hardware Supported: Internal Numeric Keypad IIe PCB (Apple part 820.0081.c), ATmega32U4 microcontroller

Make example for this keyboard (after setting up your build environment):
