Craig, no joy with the EXER 03 sequence, tried it a couple times. Same error - 04 Fail. I did notice when I clear by pressing A/B TRIG, I get 4 CRT lines and gibberish on the bottom of the screen.
pac1085, I may have to try another programmer. Do you see any need to buy $10+ worth of accessory boards and widgets?
Specific questions:
Are those resistances in the socket connections acceptable? In other words, should I reheat the the solder joints?
Thx, Ron
