Curses... all memory out, problem persists. Noted that
one of the 4116s
is missing a leg, and another has had a prosthetic leg added at some
point. Next step: turns out +5V is shorted to ground. Looks a lot like
one of the (presumably tantalum?) +5V HF noise capacitors has shorted.
Anyone know any tricks that could save me from having to unsolder and
test them one by one? There are a lot of the things, >30 at a glance.
Will persevere...
30 is not 'a lot'. It shouldn't take more than a minute to desoder one
end of one, check if it's shorted/leaky with a multimeter, and solder it
back. That's only half an hour...
