RE: Why no SOLVE & INTEGRATE commands on the 41C?
Okay  I located my first source of the 7/1/79 intro date: the Handheld and Portable Computer Club's Datafile newsletter, Vol 15 No. 6 (Nov/Dec 1996) on page 27 is Wlodek MierJedrzejowicz' "HP Calculator History  HP33C and 38C" article at the top of the page, where it begins with: "Exactly a year after their previous new model, HP introduced five new handheld calculators on the first of July, 1979. Two of these, the HP33C and the HP38C, were exactly the same as earlier models except for the addition of Continuous Memory. The other three, the HP34C, the HP37E and the HP41C, each deserve a separate article. Indeed, the HP34C deserves a whole book, and the HP41C deserves far more...."
I can surely confirm that the 41C intro date was July 16th, so there's an issue with that. We might have to consult with Wlodek as to his source of the 7/1 intro date of the other units, but at least there is another source. Jake
