Hello;
maybe I'm wrong, but it seems you wanted to address your post to HewlettPackard Company itself. In fact, this Museum and particularly this Forum are exclusively private initiative.
Anyway, about the formulas: I know the IRR and about all related financial formulas used in HewlettPackard calculators can be found at the HP12C's "Owner's Handbook and Programming Guide", Appendix D, titled "Formulas Used". This manual also refers to other specific publications in particular cases, like Standard Securities Calculation Methods as a reference for Bond calculations.
Hope it helps. But if you still need the formulas, feel free contacting me so I can send you more info.
Best regards.
