And again the self test passing with flying colors.




The AC battery charger i got with this machine has the p/n 82090B.
The battery that came with this machine has the p/n 1420-0313, Made in Japan
(Edited to correct the part number. Originally typed as 1420-0813, but closer inspection of the battery pack label gives me the impression that the correct digit is "3" and not a "8".)





For those ones who, like me, never saw it before, here is the self test procedure in a video.
The ROM checkum and RAM ability to write and read is covered during the self test. Deed dive from guru Eric Smith ( brouhaha) here.

Hello Jose , thank you for your sharing of information ; I need a rechargeable battery pack for my 32E (same as yours 1420-0313 ; the calculator does not work off the main 220v anymore ; the display while trying to charge is floating and goes off then on and does not make sense ;where can I send it for repair ? I am very fond of this calculator because i did my university entire Bsc in statistics using it ; the function for the normal distribution Q and Q-1 was remarkable at the time not having to go to the book tables ; I see that you managed to fix yours ; great job!
