#Sheepshaver mac os rom update
SheepShaver runs MacOS 7.5.2 thru MacOS 9.0. The Mac OS ROM Update 1.0 can be downloaded from Apple, but you need to have a working Mac OS system (or Classic in Mac OS X) to run TomeViewer. SheepShaver does run OS 9.0.4 with the OldWorld ROM or the NewWorld ROM on GNU/Linux, Windows or OSX hosts. On other systems, SheepShaver provides the first PowerPC G4emulator, though without MMU, to enable the execution of MacOS Classic.Performance with the current CPU emulator using basic just-in-time (JIT)translation techniques is roughly 1/8-th of native speeds.

#Sheepshaver mac os rom for mac os
Special thanks to Jason Schrader for sending me a full install CD for Mac OS 8.5. Builds of SheepShaver are available for Mac OS X, Windows and Linux. Using SheepShaver (along with the appropriate ROM image) it is possible to emulate a PowerPC Macintosh computer capable of running Mac OS 7.5.2 through 9.0.4. Downloading SheepShaver is easy, but acquiring a copy of Mac OS 8.5 took a while. SheepShaver is an open source PowerPC Apple Macintosh emulator. SheepShaver is distributed under the terms of the GNUGeneral Public License (GPL). To install SheepShaver, you need the program itself, a version of the Classic Mac OS between 8.5 and 9.0.4, and a ROM image. However,you still need a copy of MacOS and a PowerMacintosh ROM image to usethis program. The first is Mac OS Rom Update 1.0 and the second is iMac Update 1.1.Note that these ROMs are New World ROMs, and this can be used to boot only MacOS 8.5 through 9.0.4 in SheepShaver. Thatis, it enables you to run PowerPC Classic MacOS software on yourcomputer, even if you are using a different operating system. You can extract your SheepShaver ROM from one of two files. With the old world rom file SheepShaver can run System 7.5.3 through Mac OS 9.0.4, with the new world rom file SheepShaver can run Mac OS 8.5 through. SheepShaver is an Open Source PowerPC MacOS run-time environment.
