As a once upon a time Atari user and now a huge evangelist of virtualization, I found this site very interesting - marrying the two worlds.
Perhaps you've already heard of it. ARAnyM or Atari Running on Any Machine.
It is a virtual machine software for running the Atari ST/TT/Falcon operating systems (TOS, FreeMiNT, MagiC and others) and TOS/GEM applications on any kind of hardware - be it an IBM clone (read it as "PC" :-), an Apple, an Unix server, a graphics workstation or even a portable computer.
They have just announced an update to the software, a 0.9.5beta release. It brings major speed up of the MMU version. FreeMiNT with MMU or Linux-m68k can be run on an average ARAnyM machine faster than on any real MC680x0 now. Mac OS X target has been improved and many smaller bugs have been fixed.
Although ARAnyM is still unfinished, a work-in-progress and the current status is about beta it already has an interesting list of features:
- MC68040 compatible CPU (including optional MMU!)
- MC68881 compatible FPU
- JIT Compiler for CPU and FPU (speeds up CPU+FPU up to 10x!)
- ST-RAM 14 MB
- Fast-RAM configurable 0-3824 MB
- Host accelerated fVDI graphics (large highcolor/truecolor resolutions)
- Access to Host OS filesystems using BetaDOS or MiNT native XFS driver
- Ethernet networking via host using MiNT-Net XIF driver
- TOS 4.x XBIOS compatible sound (16-bit 48 kHz stereo sound)
- Parallel port (bidirectional)
- MFP, IKBD, ACIA, VIDEL, BLITTER, FDC, IDE, DSP MC56001
