DESCRIPTION

The m6502 screensaver emulates a 6502 microprocessor. The family of 6502 chips were used throughout the 70’s and 80’s in machines such as the Atari 2600, Commodore PET, VIC20 and C64, Apple ][, and the NES. Some example programs are included and it can also read in an assembly file as input.
