MachinesPlus is a tech mod which is currently in semi-active development. The final version will feature its own power system, which can be wired or wireless, with four tiers of various machines. Among the most advanced available machines will be a fully programmable computer with an emulated 6502 processor, complete with a custom assembler, disassembler, debugger, and BASIC compiler.
There have been at least two previous permutations of MachinesPlus, neither of which got far before being abandoned due to lack of planning. With a solid plan in mind, I hope that this third version will become a balanced and useful tech mod for automation and other conveniences.
MachinesPlus is licensed under GNU General Public License v3.0 and its entire source code can be found on GitHub. Currently, it is under very early development and has barely any features, none of which are very useful right now. It’s currently a low-priority project and I’m waiting for a stable version of Minecraft Forge for Minecraft 1.13.
