Onderwerp: Processor card for a HP 9835.
I am searching for a CPU card for a 9835 to replace the dead processor in my
9835A, but a CPU card from a 9845B/C would also be ok. I would prefer the
9835 card as it would be a drop in replacement but with a
9845 card I would have to transfer over the CPU module. The part number on
the module should be 5061 3001.

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 ;)
