(to quote Bugs Bunny...) Well now, I wouldn't say *that*...

You see, (assuming you have the FP with the 'programmers panel' (seven
segment displays and keypad) rather than the 'operators panel' (power
switch and run/stop/boot dial), you actually have an interesting deviation
from the 'norm' for PDP front panels.

You see, the 'programmers panel' is not hardwired to the CPU/bus like most
of the other systems are. As you watch the display and whack (gently
please) the keys you are actually talking to an (don't bonk) Intel 8008
processor, which in turn actually communicates your intents to the
system...

Now, while this would obviously not preclude adding 'bit lights', it would
be quite the interesting exercise.
