# 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.

Binary downloads (originally [from Google Code](https://code.google.com/p/mac-rom-simm-programmer/downloads/list)) can be found at https://github.com/dougg3/mac-rom-simm-programmer/tree/downloads/downloads

# Repositories

The project is spread over a few repositories. Some of them have a wiki.

# Firmware compilation instructions

As mentioned earlier, this is an AVR project that is currently optimized for avr-gcc 4.8.2. It can be built using either CMake or Eclipse with the [AVR Eclipse plugin](https://avr-eclipse.sourceforge.net/wiki/index.php/The_AVR_Eclipse_Plugin). To build with CMake:

```
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain-avr.cmake ..
make
```

This will result in a generated SIMMProgrammer.bin file which can be programmed to the board using the [Windows/Mac/Linux software](https://github.com/dougg3/mac-rom-simm-programmer.software).
