HP-32E Advanced Scientific Calculator - my first Spice machine

[jebem]

Just for fun, tried to get SQRT(-2). Got an Error 0.




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.
