# Description
This project is a bootloader and firmware for a Macintosh ROM SIMM programmer, along with control software for Mac OS X, Windows, and Linux. The ROM SIMM is compatible with the SE/30, all II-series Macs with a 64-pin SIMM socket (should include the IIx, IIcx, IIci, IIfx, and IIsi), and the Quadra 700.

This particular repository contains the main firmware that runs on the programmer board. The current compiler version used with this project is avr-gcc 4.8.2. Using a different version of gcc may result in worse performance due to some very tight optimization performed on this project to decrease programming time.
