HP-42S & 32S Compatibility
Message #1 Posted by George Rose on 29 Dec 2004, 5:02 p.m.

I am thinking of trying to get an hp42S. I have written some programs that I use at work for my 32S. Can someone tell me if my 32S programs will work in a 42S? I would like to know in advance if I am going to have to convert the progams to be 42S compatible.

Can't think of anything the 32S can do that the 42S can't do, going the other way would be a problem though with some programs.

As they are both RPN keystoke prgrammables, there should be next to nothing to do in program conversion other than the positive differences in the 42S mainly real names for programs and variables rather than single letters. You can still use the single 32S names if desired but then why get a 42S?

Be sure to get the programming examples book from the Museum CD to use the full power of the 42S menu system, thats where it makes the money well spent, IMO. Did I mention HP41 program compatibility? Two line display? Okay, so the alpha entry could be better but you'll get used to it :)

Agree with Randy, plus....

just a few (amongst many other) HP42S improvements:

ACTUAL complex arithmetic with the HP42S;
COMPLETE set of matrix tools (math, mostly, no symbolic);
concise use of the original 8Kbytes RAM (upgradable to 32K) that would make them value almost enough the original 32K of the HP33S.

A few HP42S disadvantages: no fractions as original resources in the HP42S, no algebraic expressions and no algebraic mode. I don't miss the algebraic mode, but sometimes the ability of dealing with algebraic expressions "as is" is handy...
