In the pantheon of Apple history, the Macintosh Quadra 800 (released in February 1993) occupies a significant space. It was the first Macintosh to be housed in the popular "mini-tower" form factor and represented the "sweet spot" of professional computing in the early 1990s. However, for modern preservationists and emulator developers, the Quadra 800 is notable for a different reason: its ROM.
