Quoted from LTG:Unplug the shifter connector from the bottom of CPU, if error remains you know you hurt the CPU. Switch IC's like U20 and LM339's don't show burn unless you get really creative.
LTG : )
Getting a shifter error now. Doesn't recognize in tests so must be a connection issue. Where is the connector at the bottom.of the cpu you are talking about? Does anyone know ?
Going to open it up in a minute and start checking the connections.
Thanks yall
