yes!Pins 5 and 12 should be in antiphase with each other again.
Yes!Pins 5 and 12 should be in antiphase with each other again.
yesAdjusting R14 should MOVE the trigger point of channel 1 relative to channel 2
no...with R15 can i increase or decrase CH2 pulse widthAdjusting R15 should increase (and decrease) the channel 1 pulse width.
I am desperate now!!!R14 should affect the pulse width on IC2 pins 4/13.
R15 should affect the pulse width on IC2 pins 5/12.
R11 should affect the pulse width on IC3 pins 5/12.
R12 should affect the pulse width on IC3 pins 4/13.
The trigger from IC2? drives IC2? and IC3?.

Ch2 on IC2 pin 2You may get desperate now... Only joking! Check which pins the oscilloscope probes are connected to please and report back.
Video with ch2 on ic2 pin2?IC2/2 is the synchronising pulse from the C64 modified by the level shifters on your interface board.
It is an INPUT to this circuit and NONE of the monostables on your board (controlled by the potentiometers) can EVER affect it.
Therefore is it possible you are confusing yourself by what you are seeing on the oscilloscope screen?
Is it possible to post a video of what you are observing?

This on post 1432 isnt in anti phase!I don't understand what you are saying...
What is different?
