The Emulation Realm

a mac

Shoebill is an all-new, BSD-licensed Macintosh II emulator designed from the ground up with the singular goal of running A/UX.

 

A/UX 1.x.x through 2.0.0 are supported currently, and 3.x.x support is in progress.

 

It's extremely buggy right now, very incomplete, and a little difficult to setup since you'll need to extract the A/UX kernel from your boot image (/unix).
Pro tip: (if you have an A/UX installation CD, you can boot directly from that.)
