Jim,

THe air valve are mainly in the pneumatic / hydraulic servo
mechanisms for X, Y, & Z. Air passes through holes in the paper tape
and is lead by thin pipes directly to the actuators. A small air
cylinder pushes out an 'interposing' pin and thus a binary word
representing the desired target location is set up on these pins. A
series of stacked plates engage with these pins. There is a 'set up
cycle' whereby all the plates withdraw, then try to go forwards -
some will not due to the pins. The final result is an oil passage way
through all the plates at a linear position of the target
destination. The hydraulic servo then homes on this position.

Complicated, but it worked !
