Finance - Amortization Program
Is there, or has there been an amortization program written for the DM42?

Re: Finance - Amortization Program
Hi there. I'm the one you were in touch with on the SwissMicros facebook page a couple of weeks ago. It looks like you got your DM42 fairly quickly if you're looking for programs for it now
The first program supplied on the DM42's FAT drive, amortize.raw, looks like it should do what you want. It looks like a program to run in the SOLVER.
So, load the program into the DM42's memory ([Shift] SETUP > File > Load Program > amort.raw) -- you only have to do this once, it'll stay there until you remove it with a CLP instruction.
Then fire up the solver ([Shift] SOLVER) and you should see a menu of programs that can be used. [TVM] should be in that menu. More information on how to use the solver are available in the manual for the HP-42S, which you can find here: http://www.hp41.net/forum/fileshp41net/ ... 42s-us.pdf

have you loaded "Finance.raw"? I'm not sure that's what you are asking for, but it's worth looking at.

Re: Finance - Amortization Program
You're welcome to try out this work-in-progress version I've been working on:
http://dave.brittens.org/HP42S/TVM.raw
XEQ "TVM" to start. I don't have full documentation written, but I tried to make the functionality and interface as close to the TVM and amort features of the 27S as can reasonably be achieved. It also provides programs to calculate SPPV, SPFV, USPV, and USFV, as present in the 27S solver. The programs "N", "I%YR", "PV", "PMT", and "FV" can be used in programs to perform TVM calculations.
Here's my development notes (mostly just labels, variables, flags, etc.):
http://dave.brittens.org/HP42S/TVM.txt
I'd be particularly interested in knowing whether or not I'm handling begin-period amortization correctly. Results seemed to agree with a few other calculators I compared to, but I don't know if there are certain edge cases I need to test against. None of the printing functionality is implemented yet, so the print-related menu items ("PRINT" and "TABLE") don't do anything useful.
