Pin 3 of IC 24 shows as per picture I have a GQ 4x4 programmer but as I will destroy the chip getting it out as its not socketed and I have no replacements will have to leave it in.
Do you think it is worth ordering a replacement NEC D8255AC-5 (IC5) to see if it makes a difference as I said I had to replace two legs because of corrosion.
