A programmable general-purpose computer built in Factorio. It comes with 32 general purpose registers, expandable RAM, and a separate memory for the program.
The savefile for the computer is included under the FactorioSave folder, titled Computer.zip. It can also be imported as a blueprint, see the text file full_computer.txt under Blueprints.
While no mod is required for the functionality, Pushbutton is of great help when debugging. It also lets you toggle regular constant combinators on or off without using the menu.
See the assembly quickstart guide for a quick reference on the language.
This repo comes with its own assembly language. It requires Python 3, and any file can be compiled by running
python assembly.py
from a terminal while within the "Assembly" directory. The default input file is input.fal, which can be edited with any text editing software. Any syntax errors are shown in terminal output. The output is saved as output.fal, and also copied to the clipboard (on Windows).
Adventurous people can attempt to program the computer from within Factorio, instruction by instruction. A full overview of the ISA level signal encoding for each instruction can be found in the link below.
With a new program freshly installed / programmed, you can start the computer by going to the MAN CTR (manual control) module, and turning the constant combinator labelled "START" on or off. The program counter will jump to address 0, and the computer will begin reading the program from PROM and executing each instruction.
