Good to know about the programming. I do use the Starpath Software for my Lunar observations at sea. It seems to work pretty well, although it take awhile for the processor to churn through it on the TI-91 hardware. I'm not sure what the software can do on a normal computer. I was just wondering if there was a chance to get a program on my 48GX.
The story behind the 48GX is an odd one. Throughout high school and college in the 1990's, the schools I attended used TI's. At first it was the TI-81 and then for college I upgraded to the TI-85, which had 10x the memory and the ability to do differential equations directly. I made a program to do spherical trig that I had to erase for the USCG testing sessions. Anyhow, when I graduated, I won an award that happened to be a HP 48GX. I have used it a bit over the years but have not really had a need for such a powerful calculator in my post-scholastic life. I bought the TI-89 with the Star Path software after my TI-85 went missing after one of my many moves. I now use the 89 alongside my Tamaya NC-2 and Celestecomp IV at sea these days. My NC-88 and 48GX stay at home. I do have a 48GX emulator on my phone and that is my go-to phone calculator now, but generally only for minor computations.
