The underrated hp-20s Message #2 Posted by hugh steers on 16 Mar 2009, 9:00 a.m., in response to message #1 by Frank Rottgardt
I agree, the hp-20s is a great little calculator, if you can survive without RPN.
A while back, I acquired a new one thinking it wouldn’t be long before you couldn’t buy new anymore. It struck me as a great little scientific calculator for normal use – and it’s programmable, which has become a rarity nowadays.
The screen is very clear (segments) and the keys work well. Mine had that hp quality build you don’t get anymore and reasonably priced.
All in, I think the 20b has been mostly overlooked and is generally underrated. I think this is because it doesn’t do anything particularly outstanding. However, in today’s world, most things are afflicted with some problem or other that makes things worse. This calculator does what it says on the tin and it works.
The idea of pre-storing some ROM programs for problems like solve, integrate and matrices, although somewhat of a cop-out, are actually a welcome bonus on a machine that otherwise would not have this function at all.
