Atari ST Program

.prg files are executable programs designed for the Atari ST, a widely popular computing system in the 80s and early 90s. These files enable users to store and run programs on the Atari ST system.

The Atari ST was an all-purpose computer system employed for gaming, word processing, and desktop publishing. It featured the .prg file format which could contain software programs ranging from games and utilities to other applications.

On Windows, running PRG files can be accomplished through an emulator - a software designed to simulate the hardware and operating system of the Atari ST. Popular Windows emulation options for the Atari include Steem and Hatari, enabling users to run programs from the classic system on more modern machines.

It is important to remember that the Atari ST is an obsolete computer system, and the .prg file format is not commonly used anymore. Nevertheless, .prg files may still be employed by hobbyists and collectors of vintage computing equipment.
