I bought a same kind of baby in last week:
The one I have is in perfect condition and works like a charm
Found it on a flea market and the price tag was 1€!!!!
Does anyone have this model or any other Commodore calculators? This must been one of the better Commodore calculators at the time. Wonder how much of these are still present today. Maybe it even have some value!
Oh, and it have a very nice green led numbers display that looks cool in a dark!
