OK, I'll ask the obvious - why don't you just use a 628? It's not like they are that hard to find or expensive.

Maybe some nice person will wade through your disassembly listing and fix it. However, the 628 has more I/O pins than the 629 so it's hard to say if it could even work. Good luck.
 
I am electronic man - hardware repair tv radio etc. Important for my pcb to 8 pin smd pic.
thx for answer

hi,
I would suggest you look at the pcb wiring of the 16F628 circuit before considering changing the program...
IMO there are not enough pins on the 12F.
