UAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000. A Commodore Amiga, for those who don't know, is a 16/32 bit computer system based on the Motorola 680x0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models. But if you didn't know, you probably don't want an emulator.
