Will MacLinux be able to run MacOS or A/UX binaries?
Not right now, definitely not. It has been discussed that in the future, we’ll probably be able to make a Mac-in-a-Mac using some features of the 68030+ processor to allow running of the MacOS as if the machine was a 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.
