Infinite loop

Notes: A picture of the right side of the front-panel of my Altair 8800 clone. At the top are the LEDs indicating the values of the data bus from D0 to D6 with D0, D1 and D2 looking like they are lit. Bellow that are the LEDs for the address bus from A0 to A6 with A0 and A1 looking like they are lit. Below that are the switches for 0 to 6. The data LEDs look like they are lit because of the instructions being executed only those bits are set. The address LEDs look like they are lit because the program is looping from address 0 to address 3 (11 in binary)
