OpenComputers: Rebooted

OpenComputers for Minecraft 1.21.1

Dev builds: OpenComputers: Rebooted Jenkins (Click OpenComputers Rebooted CF is adding a + instead of a space to the link…)

OpenComputers: Rebooted brings persistent, modular, programmable computers to Minecraft—along with robots, drones, servers, microcontrollers, tablets, networking, and much more.

Build computers from individual components such as CPUs, memory, graphics cards, hard drives, and network cards. Install OpenOS, connect a screen and keyboard, then program your creations in Lua. Systems can be as simple as an automated redstone controller or as elaborate as a network of servers, robots, sensors, and machinery.

Whether you want to automate a base, write your own software, construct autonomous robots, or simply make a computer beep at you because you forgot the RAM, OpenComputers: Rebooted gives you the tools to build it.

About This Port

This project is a community-maintained NeoForge port of the original OpenComputers mod for Minecraft 1.21.1.

The port remains under active development. Core gameplay is available, but some integrations and compatibility work are still incomplete. Back up important worlds before testing development releases.

Original project: https://github.com/MightyPirates/OpenComputers

Requirements

• Minecraft 1.21.1
• NeoForge 21.1 or newer
• Java 21
• ScalableCatsForce for NeoForge 3.3.3

Both OpenComputers: Rebooted and ScalableCatsForce must be installed in your mods folder.

Documentation and Support

The in-game manual is the best place to begin. The original OpenComputers wiki also remains useful for general gameplay and Lua API concepts, although some installation and integration information describes older Minecraft versions.
