Interesting HP27S Solver formulas
Hi all, I'm looking for any interesting solver formulas not really maths stuff.
Games, if any (I somehow doubt). Sorry if thats such a broad request, but I cannot find anything out there. Regards, Robin

RE: Interesting HP27S Solver formulas
Thanks for that list, most interesting.
I would love to get hold of that HP27S Technical Applications book. Regards, Robin

RE: Interesting HP27S Solver formulas
There was a scan of Popular Electronics posted a few months ago, which has Battle The Diver Bomber for the 25/25C, and I'll bet it would be simple enough that it could be implemented on the 27S (and probably even the 17BII; I wonder if the "bomber" is also a B2):
