[sdiy] divider chips and Farfisa Professional

[dragons]

Hi,
well if many of the original chips have failed it might be worth seeing 
if it is possible to make up a small pcb with some divider chips such as 
the cmos 4024 to replace them all. of course the voltage levels may be 
completely wrong...
  there are some nice photos at

I have got a professional 110 myself, so if the Divider chips ever start 
failing I'll have to look into this. the pro110 is unusual in that is 
uses electronic ( dc ) keying on the top manual, but not on the lower 
manual !
