Peter Rutenbar aea23c6dfc Implemented ftentox and fixed fscale again 
- (Badly) worked around a clang bug to implement ftentox
- (Very badly) fixed another edge case in fscale
- Found another bug in softfloat (floatx80_to_int32)
-- Not so sure anymore that my floatx80/subnormal math fix works right.
   Just figured out that x80's exp is relative to the second mantissa
   bit. float128{exp=0x3fff, man=0} == floatx80{exp=0x3fff, man=0x800...}
   even though x80 has an explicit bit, the exponents are the same...

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

  • A/UX 1.1.1 through 3.1

####Currently Implements

  • 68020 CPU (mostly)
  • 68881 FPU (a little)
  • 68851 PMMU (just enough to boot A/UX)
  • SCSI
  • ADB
  • PRAM
  • A NuBus video card with 24-bit depth

Does not implement (yet)

  • Sound
  • Floppy
  • Serial ports
  • Ethernet
  • Support for multiple screens
