I bought an HP10C some months ago (thanks, E.V.) and I did not regret. You see, the HP10C was the low-end Voyager, and many of them were bought to be given as gifts. I had a classmate (late 80's) that had an HP10C that his father was given as Xmas gift by Xerox, where he worked at that time. I remember I saw it and found no interest because I had an HP15C. About a year later he told me he forgot the calculator somewhere, maybe he dropped it in a bus. I asked if he would keep the manual, and he simply gave it to me telling "It'll be a lot more usefull in your hands, now." Well, the HP10C I bought had no manual neither box, only the original protective cover (and three new batteries! Thanks again, E.V.), but it was indeed in great shape. I keep it with the other Voyagers, now I have at least one complete series. Well, if we count the HP12C Prestige as part of the team, then I'll need one, though...
A few days ago I wrote a 33-step program that allows the HP10C to compute the four basic arithmetic operations with complex numbers. Subtraction is performed through addition with the second number entered as negative, and division computes reciprocal separately. It was just a good exercise, I enjoyed it.
