HP-71 Compu-LS module

I wrote a program many years ago on the 41c to analyze continuous beams. The solution involved solving a number of linear equations (depending on the number of spans). My first version used the PPC ROM to solve the equations (slow). The next version used the advantage ROMS MSYS function from CCD. That was a very big difference!. I'm assuming that the Math ROM will provide the same advantages. Network adjustment uses Least Squares, the matrices can become quite large depending on the number of points to be adjusted.

I'm getting the printout now, thanks Bob. I will scan the manuals and post them, give me a few days
