 41c/v/x PPC and Advantage modulesMessage #1 Posted by Joe Edwards on 11 Feb 2003, 12:35 a.m. Hey guys, I am looking at picking up some modules for my new 41cx. I am a math major and want to pick up whatever will help me out (and max out this little baby as well) in the future. I tried getting detailed info on the PPC and Advantage module, as well as the math module. Also, does the CX need a extended memory module? Any info on these modules would be appreicated. Thanks in advance. Joe

It has the solver and numerical integration as functions, rather than RPN routines, so they run faster and are more robust. These functions are the sophisticted ones implemented originally in the HP-34C and 15C. The Advantage module also has a large library of matrix functions, but is not as friendly as those in the 15C and 42S. Also: integer base converion and logical operations, complex-number operations (from the Math module), roots, curve fitting, and the financial Time Value of Money (TVM) equation, among other features. Every well-equipped 41 should have the Advantage module, but you'll need the manual or a scan (available at MoHPC). Expect to pay > \$40 on eBay for a complete Pac. If you get an Advantage module, you don't really need a Math Pac, which has the same complex-number operations, a lesser set of matrix operations, and crude RPN-based routines for the solver and integration (Simpson's Rule). It does offer a Fourier-analysis routine, hyperbolics, and triangle solutions not present in the Advantage module. The Math module contents are also available in a Math/Stat module, which combines both the Math and Stat packages in one. The 41CX has extended functions built in, so you don't need an X-functions module. You *could* utilize X-Memory modules (NOT ordinary Memory modules) for extra extended memory. If you are eager to add functionality right away, I could sell you a complete Math Pac for \$15 shipped (US). This is about the going rate, and they are as common as dirt.

I forgot about memory in the x-functions module -- thanks for pointing out my stupidity ;)
