Yes.

sensitive to power supply problems?
Very yes.
4116's need -5v from the power supply. They also run very hot. They're pretty
unreliable, and a common source of problems in machines. Not to say they're terrible -
they are good for what they are... but they are nowhere near as reliable as 4164's
Note that with a little modification, you can make 4164's work in the place of
4116's. They have almost the same pinout, they don't use -5v, and they run much
cooler.
