IIRC, the only indicator that had both pitot and static inputs
was the VSI/Rate of climb indicator and the internal bellows in the
gauge performed the differential action. Airspeed has pitot inputs
only. Baro Alt. has static port input only. Wish I could draw you a
diagram on here, it would explain everything.

Ummmm.....I think that you definately DO NOT recall correctly!
Static Pressure feeds Altimeter, Airspeed, and VSI.
Pitot Pressure feeds only Airspeed.

The Pitot Pressure from the Pitot Tube is a combination of Static
and RAM pressure. The bellows inside the airspeed indicator
uses the ambient static pressure from the static port to cancel
out the static component from the Pitot Tube leaving only the RAM
component to move the airspeed needle.
