The article states that "Basilisk II mostly emulates a Macintosh Quadra 900 (circa 1991)". This is not quite correct. Basilisk is not a pure hardware emulator, instead it patches the OS code in ROM and some resources (which can contain code in classic MacOS) in order to avoid implementing perfect hardware emulation. I guess this also speeds up the system somewhat.
