Here is the front panel board removed to get access to the bulbs. Watch out when removing or installing it that you don't bend the bulb leads or you will likely break them off. The missing bulbs in the upper left are for when more than 4K of memory is installed. Since this machine only has 4K of memory they were not installed.
