I may have spoken too soon
. It worked fine for about 3 hours and I've now got a dead CPU board. I now have the blanking LED(201) permanently on and the Diagnostic LED(203) permanently off. Think I'll wait until tomorrow to power it up on the bench and try and diagnose the problem. Anyone any pointers? Also, anyone know what current is taken from the 5V supply by the CPU board alone?
Mike.
BTW, the PLCC is 84 pins - don't know why I thought it was 100 earlier.
