The Mini vMac page linked to this today. Looks interesting:

"mosrun, short for "MacOS runtime environment", is a program that will run
arbitray MPW tools on Mac OS X, Linux, and MSWindows. The main purpose is to
run the Apple Newton developer tools, such as the cross compiler and the Rex
builder, natively and as part of a build chain. But other MPW tools will
likely run well without modification.
mosrun is a simulator for a MacOS 7.6.6 environment, paired with a Motorola
68020 emulator that will make the binaries run on other machines. Only the
first few kBytes of RAM are emulated to provide better access to MacOS global
variables. The rest of the RAM is used directly, requiring the MPW Tools to
be linked in 'far' mode (32 bit vs. 24 bit). The host needs to run in 32 bit
mode as well."
