MachinesPlus is a tech mod which is currently on hiatus until the release of Minecraft 1.14 and a stable Minecraft Forge for it. 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.
