This repository holds the source code for ARC firmware and loader, catering to New World Power Macintosh systems using the Gossamer architecture. Compatible systems include iMac G3, Power Macintosh G3, PowerBook G3, and Power Macintosh G4 PCI. The ARC firmware runs at a low level and may be compatible with Old World systems too, though currently untested. Key components such as NT HAL, drivers, and software compatibility are highlighted. Installation steps for Windows NT4 are detailed, with known issues acknowledged. Building the ARC firmware requires specific tools and device libraries. Unique dual-boot quirks, known issues, and acknowledgments are also mentioned.
