I've now managed to move the paper a bit to the right and it lines up except for 1 pixel. This was done by recreating the clock0 for DD9 as done in the P128 (your approach in post #29 was almost right solegstar)
my congratulations!!! and it is strange that my circuit does not work. The logic of both schemes is the same. a logical zero will appear at the output only when all three inputs are zero. logical operation OR 74als32 fits perfectly on a single chip, instead of two NOR and NAND.
