As it would be good to share programs for the HP15c, we have Torsten's fantastic HP15c simulator that allows to write and document programs for the HP15c.

So far it can also be used to interface with Swiss Micros' DM15 calculator, but it would be possible as well to interface with the HP15c CE, since it has a USB connection, albeit with an odd connector. The format of the HP15c CE file will be different.

This opens the possibility to create application pacs for the HP15c, with sets of programs. The simulator allows for proper documentation of the programs, and you do not need to choose anymore - you have close to 1000 program lines. Your limitation is the number of labels - just 25! (Believe me: this is a limitation when putting together many programs)

I have been considering which pacs should be created. One will be the Financial pac: I have already many programs (most of the original HP41 Financial pac), but there is room for more. I am considering including Black and Scholes, although that one belongs to the Securities pac. I am also looking for a good solution for amortization schedules, making use of the TVM existing routines.

Math Pac is more complicated: we need to think from scratch because the HP15c has already many of the features of the original pac: matrix and complex numbers!!

We'll continue with more pacs when we have finished with them - but please also reply if you want a particular set of programs be put in a particular pac.
