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.
Binary downloads (originally from Google Code) can be found at https://github.com/jpluimers/mac-rom-simm-programmer/tree/downloads/downloads
