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.

    Lets you set the number of seconds to display each program. The default is 60.
