Cool, you've picked up a bank sign! This system was used to display a
message in lights up on a pole somewhere and alternate that with the
current temperature. If its like the one I've seen there is a 2708
character ROM on the "data" board. The I played with could display a
message that is about 65 characters in length on a 32 x 16 set of light
bulbs. I checked and I don't have any data any more on the sign, I may
still have a paper tape around here somewhere.
