EPROM into MOD File

In 1987 I developed a program "GASPROP" calculating the properties of chemical gases and gas mixtures e.g. LPG and LNG. I used the MBK ProfiSet to accumulate the large program including using the special functions provided by the ProfiSet. The program was stored on a EPROM which was soled at the time. 30 years later I have made the program including leaflet, manual and program listing available to HP41.org for publishing. Now I am looking for someone with the capability to turn the EPROM content into a MOD file so it can be used with the go41cx or i41cx and published in the HP41 library. As suggested by Warren Furlow I am asking the HP41 community for help. I will provide the EPROM and all information I have (excluding the ProfiSet, which I lost in a company transfer) to someone with the technical equipment and skill set and willingness to take on the challenge.

Hi again... I haven't seen the submission on the library yet, but if you have RAW files (used on V41) I can put them on a MOD file format for you. Will that work?

Hi,
Warren stated that he is going to publish it in the next day our two. I do not have a RAW file and my printer died a long time ago. I only have the module (not private) and the program print out. I wonder if the someone has a working ProfiSet and transfer the Eprom files back into the Epromer so the files could be added to the ProfiSet MOD? I could make the printout available to you if I only would know how.

Just a statement from the person who made the EPROM GASPROP

"If you have a EPROM made for the profiset, it will work only inside a profiset because two address-lines are different to other EPROM-Boxes.
The only way to produce a MOD file will be to use a profiset with your EPROM inside and a program to generate the file running on the HP41."

So I am looking for someone with a functional ProfiSet.

And why wouldn't it be possible to *modify* those two lines to make the code compatible with all other hardware and emulators? For that matter what\s included in the module, just user code programs or also DATA tables that are read by the code??

I've looked at the manual and program listings you provided; there are at least some MCODE functions in the module for housekeeping chores (described in the manual as 'Special" functions), and probably also the unit conversion facility - which I guess must be very similar to the one included in the THERMAL Pack. Also there probably is a mass-key assignment routine performed when you turn the calculator ON - this was a hallmark back in the day.

So having a dump image of the EPROM would be required to get the complete picture. Without that one could manually enter all those programs (a real pain) but even then the MCODE functions will be missing...

Interesting challenge!
