hi kevin and steve
it should be the first moc
where the rcx would be let’s say a slave to pneumatic circuit
am i right guys
:D

Sounds like an ideal application for an RCX input multiplexer:

You can then have 12 switches on your RCX to measure two positions on each of
6 legs. Using the thermometer setting on the ports, each combination of
switches is dstinguishable as a different raw sensor value with a margin of
at least 5 counts, with 16 possible values per port. You could then plot the
leg movement on a graph!

This is very much like input multiplexor I created when inventing my first
pneumatic adding machine. The muxing was needed to create my 16 key keyboard.

You can see the resistor ladder network stack to the right of the keyboard.
Also you can see more details, including my potentiometer bricks, in this
brickshelf folder.
