Nors

Nors is a Zero Instruction Set Computer created by Calvin Games on February 14, 2017. It is Turing complete because it is equivalent to a 2-tag system.

Description

The computer state is a string of bits P.
P₀ is the initial state.
If the first bit in P_n is 1 the computer halts and outputs the successive bits in P_n.
If the length of P_n is odd then 0 is added to the end of P_n.
The new state P_n+1 is the odd bits of P_n NOR the even bits of P_n.
The computer repeats this process until it halts.

Programs

Hello World! (Outputs the ASCII code for the string "Hello, world!")
