MD/JS

Microfirmware for the SidecarTridge Multi-device by Neil Rackett

Introduction

MD/JS turns your SidecarT into a persistent JavaScript Worker for the Atari ST, enabling you to:

• Upload JavaScript source from your ST
• Call named functions with JSON arguments
• Use ES5.1, ES6/2015 and most ES2020 features
• Load text or JSON files using fetch()
• Read JSON results

Examples

Want to see MD/JS in action? Simply install the microfirmware, open the cartridge icon on your ST's desktop (lower case c drive) and run MDJSDEMO.PRG.

Plus, we've made 2 great demo apps for you to try:

MD/JS Code

A simple IDE you can use to create, edit and run JavaScript on your Atari ST!

Pong Battle: ST vs JS

A self-playing Pong demo that pits your ST against MD/JS on your SidecarT!
