SUMMARY

The discussion compares the TI-89 and HP 50G calculators, highlighting key differences in memory expansion and third-party support. The HP 50G supports SD card expansion, recognizing a maximum of 512MB, while the TI-89 has a larger library of third-party programs. Users cannot run TI-89 programs on the HP 50G, making the TI-89 a more suitable choice for those seeking extensive software options. Ultimately, the TI-89 is recommended for users who require more than the limited 2.7MB available on the HP 50G.

PREREQUISITES
  • Understanding of calculator memory specifications
  • Familiarity with SD card storage and compatibility
  • Knowledge of programming capabilities of graphing calculators
  • Experience with third-party software ecosystems for calculators
NEXT STEPS
  • Research the maximum SD card compatibility for HP 50G calculators
  • Explore available third-party programs for the TI-89
  • Investigate methods for transferring data between TI-89 and HP 50G
  • Learn about calculator programming languages and their compatibility
USEFUL FOR

Students, educators, and engineers who are evaluating graphing calculators for academic or professional use, particularly those interested in memory expansion and software capabilities.

The main difference between the two (other than the RPN which I don't care much about as I am already used to using a TI-83 which doesn't have RPN) is that the HP is powerful, and the TI has more 3rd Party support. Of that though, the things I care about most is that you can expand the memory of the HP 50G with an SD card, and that TI-89 has many more 3rd programs than the HP 50G. So basically, I'm wondering a few things.

What is the maximum recognizable of space on the SD card? If I put a 4GB card in the HP 50G would it recognize 4GB? I wouldn't use 4GB, infact, I don't see how I'd use more than a few extra MB, but I was just wondering, how much could be recognized?

Is there a way that TI-89 programs can be run on an HP 50G? It probably sounds stupid, but I was thinking maybe there's some way to install something that allows it to run the programs of other codes.

Will I really need more than the space aviable on a TI-89? I'd like to have a few games, and some programs for certin subjects and some notes and stuff, but I won't have huge amounts of stuff. And I could rotate what I have on there, but 2.7MB just doesn't sound like a whole lot.

The max for the SD card is 512MB. You certainly won't need more than that.

I don't think Ti programs can run on an HP.

From your post it looks to me like you should get a Ti.
