Thanks for your attention.
I found this project on the internet:
http://gregorkarnas.com/radio/projekt/nixieclock2/index.htm
But the links are not working, so I was not able to find the Hex code to program the PIC. Looking on the internet I found this forum and in one page o found the file nixie_0_sq8cby (I suppose to be the same hex code for the PCB showed in the link above). I built the pcb but the clock is not working. I am using Z560M tubes, not the same tubes used in the original project (Z573M), but wiring in the correct way there is no problem here. But there is something wrong.
When powered the tubes turn on but not I was expecting. The first tube shows one number (but the others not), the first tube turns off and the second tube turns on and shows one number (but the others not), the second tube turns off and the third tube turns on and shows one number (but the others not), finally the third tube turns off and the fourth tube turns on and shows one number (but the others not), and the loop starts again. Whats is wrong?
I want to build this clock:

But as the link in the page its not working, can somebody to provide the hex code for this project?
Thanks
