I've just received an HP-41CV and a few modules, for the cost of shipping.
The calculator is in very good condition- cosmetically, that is. I hope I can repair it.
I've installed a known good battery pack from another 41 that I use, but the HP-41 mentioned above does not turn on.
The contacts inside the calculator look very clean.
Would someone point me to some troubleshooting steps? I hope to narrow down which part(s) are bad, and decide to repair it
or sell it for parts.
