> After one year of struggling with my jdm programmer I was finally able to get it working. It has a 18 pin socket for a 16F84A. What do I need to add to make it work with a 16F628??? A 16F628 should work fine. Just use software that supports it (IC-prog works, for example). Note that a 16F628A might not work (although my JDM handles 16F628A with no problems).
