Please, allow me to ask: is there anything in particular that the MONEY program in the HP41 Financial pack has that you need OR you need the MONEY program functionality as it can be found, for example, in the HP12C or any other financial calculator? I am asking about this because the HP41 standard applications pack has a financial calculator that computes N, I, PV, PMT and FV almost the same way MONEY does. It does not have all MONEY features, but these first five financial variables can easily be computed. The financial calculator program itself has no main label, uses registers R00 to R09 and has 201 program steps (did not find how many registers).
What I want to point out is the fact that chances are you may find other programs that might be easier to load in the hP41CX and would give you all functionality you may need from MONEY, and using less memory. Programs in ROM tend to use more bytes and have extra functionality that may not add much specific computing resources for the main subject. The Financial Module for the HP41 has some extras not found, for example, in the HP12C, like the interactive selection for BEGIN/END, or clear existing data, or messages like READY. Nevertheless, the HP12C offers that much financial computing resources with almost no interactive operations and almost no messages (only the Error n standard ones).
The HP34C application programs handbook has some examples of financial programs that might be ported to the HP41CX, too. There is also the HP-41C Financial Decisions Pac, available with the MoHPC CD/DVD with some related subject. The programs in these pacs are listed so you can key them in.
