Peter Rutenbar f04e039dca Promoting newfpu to be the current fpu (aka fpu.c) 
Just merged the newfpu branch to master, almost everything
is implemented, but there are clearly lots of problems still.

(According to xcalc, sin(3.1415927) == 0.054803665, which is
pretty far beyond the acceptable error margin.)

Shoebill

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

####Supports
