A Macintosh II emulator that runs A/UX
Go to file
Peter Rutenbar c8e7ba594c Implemented fatanh,cosh,etox,etoxm1,lognp1,tanh, and twotox
but not ftentox, because this hits a clang bug. Clang 3.5
(and earlier?) wants to optimize pow(10.0, x) to
__exp10(x), but __exp10() doesn't exist in the 10.8 SDK,
so the linker fails. There's probably some simple workaround...

A Macintosh II emulator that runs A/UX (and A/UX only).

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

Shoebill requires a Macintosh II, IIx or IIcx ROM, and a disk image with A/UX installed.

Download the latest release, and then see the getting started wiki.
Also check out screenshots.

Update (Oct 15, 2014): Sorry there hasn't been a new release in a while. Ethernet is mostly-working in the latest source tree, and I'm currently working on a total FPU rewrite. I'll release 0.0.5 when the new FPU is mostly-working
