# Emulated Woz Machine

[![Build Status](https://travis-ci.org/st3fan/ewm.svg?branch=master)](https://travis-ci.org/st3fan/ewm)

## Introduction

Two years ago between christmas and new year I wrote a tiny and incomplete 6502 emulator and turned it into an original *Apple 1* emulator. It was a fun and nostalgic project to work on. I grew up with the *Apple II* and never had a change to see an *Apple 1* in action.

A few weeks ago I decided to pick this project up again. I am extremely motivated to turn this into a high quality emulator that supports the *Apple 1*, *Replica 1*, *Apple ][+* and *Apple IIe*. Some of that work is really close to being finished, other work will take many months of spare time hacking.
