Hi all,

I'm interested in using the extra program space in the 12CP to store
some trig, etc, functions so I can use the new hardware as a scientific
calculator.
I have a 15c but would like to avoid trashing it 'in the field', so a
12cp would seem to fit the bill.
Are there any issues with being able to access all the memory present in
the unit? (I seem to remember some issues like this were aired a while
back.)

Am I wasting my time?

ttfn and thanks in advance

Because you don't want to break the 15C?

(1) I will trust a good old 15C much more than any of the crap from HP
in the last five years, 12CP included.

(2) The 15C is the calculator of choice for those things ... Unless you
can find a 42S.

Could point, Thierry!
BUT if Jason insists, the new large memory of the Platinum enables it to
have trigs
Use google to search and also take a look at hpmuseum Forum article archieve

Tony Hutchins found such a bug, which I described this way:
http://groups.google.com/groups?selm=7fcf10a1.0306050213.60ea54f3%40posting.google.com

Dunno if this has been fixed, though.

Trigs do fit in the old 12C anyway: see Datafile V20N5p45, V21N1p21
and V21N1p12.

Valentin Albillo has produced a 99 step program (so it will fit into a
original 12C) that generates sin, cos, tan and their inverses with
maximum accuracy. It appeared in V21N1 of Datafile in an article
entitled "Tried and Tricky Trigonometrics".

You can get a copy by ordering the "Twenty-One Years of Datafile" cd
from Jake Schwartz on http://www.magpage.com/~jakes/ppccdrom.htm

Or join HPCC (www.hpcc.org) and order a back copy.

Soooo, I take it that people are saying (a) why? but (b) it can be done...

I know it's a strange approach, but I like the voyager form-factor too
much to trash my 15c 'in the field', so I think I'll give it a go.

Thanks all.
