Pneumatic sequencer. Help needed !

[TechnicHead41]

Hello everybody !

Need some sort of a solution or diagram to make

my six legged pneumatic walker to move.

This is what i've got.

And this is what i have to end up width this

for it to walk, this controls two cylinders. It makes one to extend, then wait to the second one has

extended. first one to retract and then the second one to retract, then it starts all over again.

Can some one help me width a diagram of some sort ???

perform as expected.

attached the output A and B cylinder.

It would be great if anybody can help me deciffer the last picture.
