"When Steve Jobs announced Apples transition to Intel's x86 processor line, a huge stir occurred among some Mac OS X users who depend on 'Classic' the OS9 environment in Mac OS X for their day to day Mac usage, as Mac OS X on Intel means no more 'Classic' and they were right. Rosetta allows PowerPC applications to run on x86 through JIT (Just In Time) architecture emulation, but its translation is not on a low enough level within OS X to allow 'Classic' to work on x86 and as such those among us who use OS9 applications have been left out in the cold. Until now that is: a project called 'Sheep Shaver' was created to allow BeOS on PowerPC emulate the PowerPC architecture to run another PowerPC operating system on top of BeOS. This application was ported to Mac OS X with the demise of Be Inc. and has since been ported to Mac OS X on Intel processors."

Mac OS Runtime Environment for BeOS
A few web sites have news about SheepShaver Mac OS Runtime Environment for BeOS which lets the BeOS run Mac applications. However they say that SheepShaver is a Mac OS emulator. But the creators of SheepShaver say it is not an emulator of the Mac OS! I found this out when I asked the makers of SheepShaver the question "Do the makers of SheepSaver have a license from Apple giving them the right to make SheepSaver look exactly like Mac OS 8?" The makers answered by saying that "SheepShaver forces MacOS to run as a thread of BeOS. What you see at the screenshots is the real MacOS 8. SheepShaver just uses your old installation of MacOS on your Harddisk." It runs with any version of Mac OS 7.5.2 and greater.
Are there plans to develop SheepShaver for Intel x86 and/or Windows that includes a Mac hardware emulator? The makers said "if we find a fast PPC Emulator for Intel, it should be possible to run all MacOS apps with BeOS Intel." Their method of running the Mac OS seems very similar to Apple's method of running the Mac OS (blue box) on Mach/OpenStep in Rhapsody. It also seems similar to Windows95 running on VirtualPC running on the Mac OS. It looks like Mac OS may be coming to Intel, one way or another.
Are there plans to develop SheepShaver for other PowerPC OS's? Marc Hellwig (one of SheepShaver's coders) said "Perhaps LinuxPPC (not for sure ... a matter of free time)."
What does the name "SheepShaver" mean? Marc Hellwig said "the second coder involved in SheepShaver, wrote a Mac Emulator for the Amiga called ShapeShifter (out of the C64 game archon). At a meeting of Amiga freaks someone called him a "SheepShaver" and we liked this name."
"
were do you think this Rosetta/JIT (Just In Time) architecture emulation coding idea became popular?, thats right, the Amiga/Emu coders such as the shape shifter,UAE,etc...
its nice to see the other platform coders finally catching up with the past....
