The full story
A developer used Claude Code to turn classic Macintosh ROM listings into a commented source tree that can be assembled with modern tools.
The forum post describes expanding the work across the Macintosh 128K, 512K, Plus and SE and reports byte-identical reconstructed ROMs. It links to the reverse-engineering project rather than describing a newly designed replacement ROM.
