Hi, Gene;
thank you to remind me... I was almost sure it was you, but I was affraid giving the wrong credits.
BTW, I wrote an interface for the HP48/49 (User RPL) that emulates almost all of the functionalities found in the HP12C when dealing with cash flow analisys, I mean, data input and edition. I borrowed someone else's computation for IRR and NPV to test the interface, so I cannot disclose it publicly. Anyway, I'd like sending you a copy of it so you can tell me what do you think of the interface itself. I'll write my own IRR and NPV routines soon, but having your opinion and necessary suggestions would surely help improving it.
I have lost almost all of my contacts e-addresses, and I cannot find yours, too. So, if you can send me an e-mail tellin me if you'd like to test it, I'd send you a copy of it. I searched hpcalc dot org and found some advanced libraries, but have not found such HP12C-based interface.
If so, please send an e-mail to:
lcviera at quantica dot com dot br (I guess you still have it, right?)
I'd also add some news related to that contact with HP, A.G., remember?
Best regards, Gene. Please, feel free deleting this message after reading: the password is my midname, all lowercase, no accented letters.
Cheers.
