I just picked up one of these today but I didn't
get the power cord.
Does anyone of the list have one and if so can you tell me the pin out
of the power connector? It has three pins and I beleive that the
caclulator can ran off of AC or low voltage DC. Here is a picture and
article of the same model calculator

Joe, the 3-pin receptacle on the calculator accepts a cord from either
of two external power units. One being a unit that works off of 12vdc -
cigarette lighter - and the second works off of 110vac. The second unit
is capable of 8.7vdc @ 150ma as well as 9.6vdc @ 230ma. There are a
couple of charging modes as well as a charge while running on external
power and my suspicion is that this accounts for the 3 pins on the
connector. I will see if I can get something more definitive for you.
