The biggest board I ever made was for an eight channel lighting controller
for a small amateur dramatic society I was involved in. This was pure
analogue, output 0-10V DC, to control separate dimmer boxes and came out
about A4 paper size - which was just as well since that was the maximum
mask size I could print and the size of my commercially made light box.
