VICE is a program that runs on a Unix, MS-DOS, Win32, OS/2, Acorn RISC OS, BeOS, QNX 4.x, QNX 6.x, Amiga, GP2X, SkyOS or Mac OS X machine and executes programs intended for the old 8-bit computers. The current version emulates the C64, the C128, the VIC20, almost all PET models, the PLUS4 and the CBM-II (aka C610).
