That's because analog and digital boards were designed by 2 people with completely different background and habits. One of them was Bob Moog. Now guess which was the one he did :) About failing chips, there might be several causes. Could be damaged by ESD at some point during storage or delivery or during assembly, or one (or more) process during manufacture was badly adjusted, or it was overstressed in the circuit and later they used different part, or they used vintage chips found at the back of a barn that were not really good even when new, or electromigration causing all chips to die eventually. Or all of this combined. What was the chip they refer to as the one failing regularly?

Can through-hole stuff be done and automated by assembly houses still? Second question: I guess I always assumed that an IC would either work forever under normal use. What might have happened to these batches of IC's that Moog got in these Voyagers that would cause them to stop working only years down the road..
