Solver, HP Solve, etc.

[HP67]

I had found this article from the hpcc. They are usually pretty good at getting the facts right.

http://www.hpcc.org/calculators/HP30b_review.pdf

and this thread from the old forums here:

http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=164656

and this at Datamath http://www.datamath.org/Related/HewlettP.../HP30B.htm

and here in the HP doc on page 87 http://h10032.www1.hp.com/ctg/Manual/c02651527.pdf

But it's not real descriptive (only one page) and I suspect older manuals and or articles have a lot more info on it.

Edit: thanks, Massimo. That's more than I had.
