TIS-3D
by Sangar
TIS-3D is a Minecraft mod that adds low-tech programmable computing, where players build multi-block computers from small nodes called modules.
What it does
Each module is a small programmable node, and the mod expands the third dimension by letting players connect them into computers in a varied, open-ended way. The design is inspired by the game TIS-100. An execution module runs an assembly-like program written in a dialect introduced in TIS-100, and a few extra quality-of-life instructions are added on top of it. A redstone module reads and writes redstone signals, which gives programs basic interaction with the world.
Other modules are more specialized. A stack module provides a small amount of data storage, an infrared module sends data wirelessly between TIS-3D computers, and a terminal module handles rudimentary text input and output. Programs can be written in a vanilla Book and Quill or on Code Bible pages, and copied back to Code Bible with a sneaking right-click on an execution module.
TIS-3D is open source under the MIT License. It is published for Fabric, Forge and NeoForge across 8 release versions, 1.18.2 – 1.21.11, and runs on client and server, so both the server and every player need it. Architectury API, Fabric API, Forge Config API Port and Markdown Manual are required dependencies. Four mods build on it, among them TIS-VS, TIS-Create and TIS Advanced.
Key features
Modular multi-block computers
Players combine individual modules into computers of their own design, with no fixed layout required.
TIS-100 style programming
Execution modules run programs in an assembly-like dialect introduced in TIS-100, extended with a few added instructions.
Redstone interaction
A redstone module reads and writes signals, so programs can automate tasks that would otherwise need redstone circuits.
Stack and infrared modules
A stack module stores a small amount of data, and an infrared module passes data wirelessly between computers.
Terminal module
A terminal module gives programs rudimentary text input and output for interacting with the player.

What the author says
TIS-3D is a Minecraft mod inspired by the brilliant game TIS-100 (buy it, seriously). It takes the concept of minimal, programmable nodes (called "modules" in the mod) and expands it to the third dimension. This allows building multi-block computers from different modules in a super-flexible manner. Some generally…
