> To summarize, Mel enabled the index register bit (despite not using the index register) to cause an integer overflow, and because the instruction was at the very top of memory, it had the side-effect of also incrementing the instruction’s opcode, modifying the instruction to change into a JUMP command, in order to exit an infinite loop.
