Hello Aurelio,

I am doing well, and you?

I've opened the case and removed and reinstalled the PCB. If I flex the calculator I can get the Memory Lost display. I suspect a bad solder connection somewhere. I'll need to put it under the microscope and do and inspection. The seller reported that he was able to run the self-test and received a URAM failure. If that's the case then I'll replace the RAM with a 32K chip. Anybody have a part number?
