I was bored and found a HP-27S

You seem to have collected a lot of info on the solve application and history. Would you mind posting a bibliography and/or any links to info on this? I'm trying to find reading material on the subject and I'm sure many people would find it useful.

I do have the Museum DVD so I am putting the HP-27S/19B Technical Applications doc you referenced on my reading list.

Thank you.

The Solve function on the vanilla 30b (and many other HP calcs) is not the same as the Solver on the 17b/17bii/19b/19bii/27s/and others. As I think the other thread mentioned, the solve function that started out on the 34c (I believe) requires you to write a little RPN program and then "solve" the program. I know very little about that solver, my interest has always been in the 17b-type solver that includes programming things like loops, decisions, variables, and so on.

I don't really have a bibliography or a list of references, but the HPMuseum forum (and its original forum) have plenty of discussions about the 17b-type solver.
