OpenComputers Documentation

OpenComputers provides a suite of persistent, modular, and highly configurable devices that can be programmed using Lua 5.2.

Core Device Types

• Computers: The primary base for systems. They feature modular components and can access components via six faces. Component capacity is limited by the processor level.
• Servers: Designed for higher complexity. They can connect to more components (both internal and external) using component buses. However, due to the server rack, a server can only access components through a single face of the rack as configured in the server rack interface.
• Micro-controllers: Highly limited devices. They lack hard disk (HDD) and disk drive slots, meaning OpenOS cannot be installed on them. Instead, they use an EEPROM for specialized, limited-task operating systems.
• Robots: Mobile computers capable of interacting with the world. Unlike computers, internal components cannot be swapped once built unless the robot is equipped with an upgrade container or a card container. OpenOS can be run on robots via a disk drive (using floppies) or a pre-installed HDD. To completely reconfigure a robot, it must be passed through a disassembler.
• Drones: A limited version of robots. They have different movement mechanics, fewer inventory slots, and no operating system (they use EEPROM for specific tasks instead).

Key Concepts

• Persistence: Computers, servers, robots, and drones are persistent. They maintain their state even when the chunk they are in is unloaded. Tablets are the only exception to this rule.
• Modularity: Most devices allow for component swapping via their respective interfaces. For robots, use containers to allow hot-swapping of cards or upgrades.
• Interoperability: Devices can interact with other Minecraft mods for block/entity manipulation via an adapter, or through specific robot or drone upgrades. They support various energy types including Redstone Flux (RF), IndustrialCraft2 EU, Mekanism Joules, Applied Energistics 2, and Factorization charge.

The block index provides a categorized overview of all documented blocks in OpenComputers. Note that some blocks may be unavailable depending on the specific recipe settings of your modpack.

Blocks are categorized into:

• Computer: Main computing units like cases, microcontrollers, robots, and server racks.
• Komponenten (Components):
  • Eingabe / Ausgabe (I/O): Input and output devices like keyboards, screens, and hologram projectors.
  • Speicher (Storage): Storage solutions like disk drives and RAID systems.
  • Extensions: Specialized hardware like adapters, geolyzers, motion sensors, redstone I/O, and waypoints.
• Montage / Druck (Assembly / Printing): Tools for manufacturing such as 3D printers, assemblers, and disassemblers.
• Netzwerktechnik (Networking): Connectivity tools like cables, net splitters, and relays.
• Energiemanagement (Power Management): Power-related components like capacitors, chargers, power converters, and power distributors.

The item index provides documentation for various tools, devices, components, and crafting materials used in OpenComputers. Note that availability of specific items may vary depending on the recipe set being used in your environment.

Items are categorized into:

• Tools: Utility items like the Analyzer, Manual, and Remote Terminal.
• Devices: Standalone hardware such as Drone, Server, and Tablet.
• Components:
  • Cards: Expansion cards like Graphics Card, Internet Card, and Redstone Card.
  • Upgrades: Functional enhancements like Battery Upgrade, Chunk Loader Upgrade, and Inventory Upgrade.
  • Rack Mountables: Items designed for server racks, including Disk Drive and Terminal Server.
  • Other: Core hardware like CPU, RAM, Hard Disk Drive, and EEPROM.
• Crafting: Materials and sub-components required for assembly, such as Circuit Board, Microchip, and Transistor.
• Assembling / Printing: Items used in the manufacturing process, such as Ink Cartridge and various device cases.

If you are looking for information on blocks rather than items, refer to the block index.

The OpenComputers item index provides documentation for all items in the mod, categorized by their function. Note that availability of certain items may vary depending on the Recipe Set being used in your modpack.

Items are organized into the following categories:

• Werkzeuge (Tools): Specialized tools like the Analyzer, Manual, and Wrench.
• Geräte (Devices): Main hardware units such as Drones, Servers, and Tablets.
• Komponenten (Components):
  • Karten (Cards): Expansion cards for various functionalities (e.g., Graphics, Internet, Redstone, WLAN).
  • Upgrades: Specialized modules for devices (e.g., Battery, Chunkloader, Solar Generator, Inventory).
  • Anderes (Other): Core hardware like CPUs, RAM, EEPROM, and Storage (Floppy, HDD).
• Crafting: Materials and sub-components used to build hardware (e.g., Microchips, Circuit Boards, ALU).
• Montage / Druck (Assembly / Printing): Consumables and housings used in the assembly process (e.g., Chamelium, Ink Cartridges, Drone Cases).
• Anderes (Other): Miscellaneous items like Hover Boots.
