HP-25



#6

What is the maximum voltage that can be used on HP-25?


#7

Unofficially, I'd say at least 3 vdc, since I've used AA alkaline 1.5 vdc cells w/o any problems.

Hi Roberto,

do look up this discussion http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv011.cgi?read=29484

the answer suggested is 3,2Vcc.
