Fuse (the Free Unix Spectrum Emulator) was originally, and somewhat unsurprisingly, a ZX Spectrum emulator for Unix.
However, it has now also been ported to Mac OS X, which may or may not count as a Unix variant depending on your advocacy position. It has also been ported to Windows, the Wii, AmigaOS and MorphOS, which are definitely not Unix variants.
What features does it have?
- Accurate 16K, 48K (including the NTSC variant), 128K, +2, +2A and +3 emulation.
- Working +3e, SE, TC2048, TC2068, TS2068, Pentagon 128, Pentagon "512" (Pentagon 128 modified for extra memory), Pentagon 1024 and Scorpion ZS 256 emulation.
- Runs at true Speccy speed on any computer you're likely to try it on.
- Support for loading from .tzx files, including accelerated loading.
- Sound (on Windows and Mac OS X, and on systems supporting ALSA, the Open Sound System, SDL or OpenBSD/Solaris's /dev/audio).
- Kempston joystick emulation.
- Emulation of the various printers you could attach to the Spectrum.
- Support for the RZX input recording file format, including 'competition mode'.
- Emulation of the Currah μSource, DivIDE, Fuller audio box, Interface 1, Kempston mouse, SpecDrum, Spectrum +3e, ZXATASP and ZXCF interfaces.
- Emulation of the Beta 128, +D, Didaktik 80/40, DISCiPLE and Opus Discovery interfaces.

What is it lacking?
- Quite a lot! However, it's a lot better than it used to be...
