Macintosh ROM SIMM programmer

This project is a bootloader and firmware for a Macintosh ROM SIMM programmer, along with control software for Mac OS X, Windows, and Linux plus a Windows INF USB driver. 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.

The programmer and software supports 2 MB and 8 MB SIMMs.

Schematics and PCB layouts for the ROM SIMM and the ROM SIMM programmer are also available for non-commercial use.

No ROM images will be distributed; this is a tool for personal exploration.
