HP calculators sales volume

[Andres]

Hello all!

I'm working on a university assignment about the first HP pocket calculators, and I wonder if someone here may have a rough estimate of the number of units sold, specially for the first models (mainly those on the Classic and Woodstock series; Spice and Coconut quantities may also be nice to have). I learnt that the break-even ponit for the HP-35 was 10.000 units but it sold 100.000 units on its first year!

I'm usually interested about technical aspects, but this time I need more business-side data.

Thank you very much in advance, best regards.
