The Abterra I is a computer built in minecraft without the use of any command blocks or mods. This computer differs from other minecraft computers in a few ways:
- Small and simple instruction set.
- Instruction and data stored in the same place.
- Programs can be written from the control room.
To actually figure out how the machine works and how the computer works and how to program it download the manual at https://www.kznarsk.xyz/abterra/AbterraI%20manual.pdf
The minecraft computer itself is not on this github page, because it is not a text document.
