"1.0 R5" . . "Basilisk II is an emulator which emulates the 680x0-based Apple Macintosh computer on a variety of operating systems.The last version of Mac OS that can be run within Basilisk II is Mac OS 8.1, the last 680x0-compatible version. Newer Mac OS versions are not compatible because they require a PowerPC-based processor, which Basilisk II cannot emulate."@en . . .
