We have a Turing Complete CPU in this episode implementing conditional jumps and a test program. No, it doesn't catch fire, but I do build a test program that halts if the processor errs :-) This is in a CPU built from scratch using Digital, a digital logic simulator that can be used to build a CPU that can run on an FPGA.
