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.
