Going to the right, the next switch was the RESET/STOP switch. Pressing STOP caused the CPU to halt after completing the current instruction. Pressing RESET caused the CPU to halt immediately, cleared a number of CPU internal registers, and sent an I/O reset signal to all connected devices. The switch to the right of that was the START/CONTINUE switch. Pressing CONTINUE caused the CPU to resume executing at the instruction currently pointed at by the program counter. Pressing START transferred the value currently set in data switches 1–15 to the program counter, and then began executing from there.
