      @djsundog It's true. With sufficiently clever hardware, any Forth environment that implements *only* @ and ! is now Turing complete.

      Not even joking.

      My S16X4 family of CPUs implemented 12 instructions originally: NOP, # (literal), @, !, AND, XOR, ADD, and ZGO (jump if zero), C@, C!, GO (unconditional jump), and NZGO (jump if non-zero). That's it.

      The Steamer16 (from which S16X4 is based) implemented only the first 8 instructions listed above. ;-)

      @djsundog please spare me, oh dangerous Forth implementer
