Pythaeus writes to tell us that although Apple has developed a new 68040 emulator for the Power Macintosh that reportedly runs twice as fast as the emulator, the new emulator cannot run on existing Power Macs due to ROM incompatibilities. The problem apparently lies with having too many 68040 cache-flushing calls in the current Power Mac ROMs, and those calls destroy the performance increase of the new emulator. These calls will be fixed in future Power Mac ROMs, but the new emulator code won't work on current Power Macs. [ACE]
Thoughtful, detailed coverage of the Mac, iPhone, and iPad, plus the TidBITS Content Network for Apple consultants.
