Arduino is wired straight to the panels, but in the original config it 
went thru this midplane board.

The midplane splits the data from the original CPU into the panels in that 
sign, and also to the DB25 that passes it to the next sign.

Some of it obvious that it should work easily, but attempts to drive more 
than one didn't work.

Probably a matter of looking up the chip #s, and drawing otu what they do 
on a white board or paper. Should all be buffers to help keep the signal 
clean.

Another big ? is, does the arduino have enough power to receive data on 
serial while keeping the sign refreshed, or will it glitch if it's picking 
up incoming data.
