Trinity was my first test of making a computer in Minecraft. It was the result of several iterations of a design for an ALU, and took a long time to make.
ADD
, JMP
The ALU is very simple in Trinity, as it only has an add function. This is made with the binary adders, shown in purple.
The memory uses D type flip-flops, which are made with redstone torches and repeaters.
The program counter is a 4 bit D flip-flop, used to store the current program location. The circuit behind it increments the program counter to advance the program.
