Will Linux/mac68k be able to run MacOS or A/UX binaries?
Not at present. It should be possible to make a Mac-in-a-Mac using some features of the 68030 and later processors that could boot MacOS on a virtual 68020 (since the 68k architecture is virtualizable, unlike i386). Honestly, it’s more important to get as many systems as we can running Linux right now than to get them running MacOS. If you want the MacOS that bad, what are you doing here? 🙂 A/UX is uncertain. We haven’t looked into it enough to make any judgments. Part of the reason for this is that A/UX is very hard to find. Personally, I (dhd) am much, much more interested in the possibility of being able to run 68k HP/UX and SunOS binaries like NetBSD and OpenBSD can. In general, if you want binary emulation that actually works, NetBSD is your best option on any architecture.
