This project borrows heavily from the *awesome* work of Andrew Holme and his ["Pool"](http://www.aholme.co.uk/6502/Main.htm) project and [Arlet Otten's](https://github.com/Arlet/verilog-6502) tiny 6502 core. Also many special thanks to [sbprojects.com](https://www.sbprojects.net/projects/apple1/index.php) for the wealth of information I gleaned from there.

## Helping
All PRs and suggestions happily accepted! Please any support us most welcome, and it would be good to have this as feature complete as possible with the real Apple1. I'd like to implement the cassette interface next with the basic electronics to talk to the headphone/mic jack of a mobile phone to upload and download recordings as a means to save programs.
