Hp 48gx software

[Johann]

I am looking to buy calculus and physics software, for a HP 48gx. I am unable to find any except on ebay. Does anyone know of a website or person that is willing to sell any of these.
Thanks

Get a memory card and put on erable/alg48.

It will probably be cheaper for you just to buy a hp49g+ or ti89. These can do symbolic mathematics without external software, and offer a boost in speed and better screen (but a poorer keyboard)

I also recommend to buy the faaast HP 49g+.

Look for programs at www.hpcalc.org
