Front-window bakery material. Catches the eye, delivers the goods.
Summary
This GitHub project documents an experimental modification to run a Motorola 68060 CPU in a Macintosh Quadra 650/800/Centris 650 computer using ROM modifications. The project achieves basic functionality allowing the system to boot an unmodified System 7.1 installation, but many features remain non-functional. The creator emphasizes this is a proof-of-concept only, not intended for practical use, and warns against attempting replication.
Key quotes
· 3 pulledThis project is a collection of ROM modifications to get a minimum level of functionality out of a Macintosh Quadra 650/800 / Centris 650 with a Motorola 68060 CPU installed on an appropriate adapter.
As currently sits it can boot an unmodified System 7.1 install. Much will not work and further work is required to bring into a truly usable state; I do not expect to finish it.
This is a experimental proof of concept ONLY. Do not expect it to be usable! Please don't rush out to replicate.
