Atari ST
The Atari ST was a 16 bit home computer that was very popular in the late 80's and early 90's.
It was the direct competitor of the Commodore Amiga and both machines were based upon the 68000 CPU.
It was first released in 1985 and was very sucessful in the professional music industry due to having MIDI
ports as standard.
EstyJS 2.0
EstyJS is an emulator for the Atari ST, written in 100% pure JavaScript, originally developed by Darren Coles. Since 2024 and the release of EstyJS 2.0, the project is maintained by Kai Eckert. The source code is available on GitHub. Please use GitHub issues for feedback, bugs and ideas.
EstyJS is not a full emulation and focuses on running games or old software for demonstration purposes. Notable limitations:
- No writing to floppies.
- Only partial support of keyboard/mouse/joystick.
- Timer pulse width & high accuracy < 1 scanline is not supported.
- No border effects (as used by some demos), only the official resolutions are supported.
Usage
- Use the "Browse" buttons to load a floppy image (.st or .sts files are supported)
- Use the middle mouse button to realign the mouse pointer if necessary.
- Joystick 1 is emulated using cursor keys and ctrl (or a real usb joypad).
