Hi Paul, I think I have a HP 9845 board somewhere, but did you checked the connection between the processor and the pcb. It's made by a combination of polymer with gold wire on it. This is the first time I heard of a bad processor, there is a much higher change of bad connections than of a defective processor. The connector principle is the same as in the HP-41C from where it's known to cause some trouble. Let me know the outcome if you're sure it's the processor I'll dive in to my parts stack ;) -Rik
