What was the 1st CAS pocket calculator?
...in any format or specification.
What was it? And what was the 1st CAS calculator model from... HP? Casio? Texas? Others? Can't find any certified information on this. Thanks in advance. Jose Mesquita RadioMuseum.org member

Hello!
According to the wisdom of Wikipedia (and my own memory as well) this was the HP28C (https://en.wikipedia.org/wiki/Computer_algebra_system). Regards Max

The first CASIO able to do symbolic manipulation was the FX5500 from 1986.

RE: What was the 1st CAS pocket calculator?
Symbolic manipulation is not properly a full CAS engine, are some subroutines or functions on numerical kernel
This is my list of CAS history about calculators. 1: The first complete CAS engine in a calculator was incorporated in the TI68K series (TI92 of 1995) then in the TI92+, TI89, TIVOYAGE200 and in a new series TINSPIRE as (TINSPIRE [CX] CAS). I suggested to Texas Instruments that they add the acronym CAS in the TINSPIRE and they accepted my request =) https://en.wikipedia.org/wiki/TI92_series The Texas Instruments company bought the famous CAS DERIVE (DOS) and port the source code to run on a MC68000 motorola processor aka m68k, and then on the tinspire, so the DERIVE never died =) 2: The HP49 (1999), I say that included a CAS but very basic, ERABLE, the first works of our great friend and programmer BERNARD PARISSE, Then ERABLE evolved in xCAS https://en.wikipedia.org/wiki/HP_49/50_series#50g 3. In 2003 CASIO released the ClassPad 300 Somewhere I read that it has the engine of MAPLE IV, I would like to know that someone confirms it me. https://en.wikipedia.org/wiki/Casio_ClassPad_300 4: In 2013 HP released the HPPRIME with XCAS as the engine, is becoming the best CAS mounted on a calculator, if there were more developers XCAS parallel could even compete with MAPLE and why not with mathematica https://en.wikipedia.org/wiki/HP_Prime 5: waiting 201x for SHARP or another developer to launch a calculator with CAS and only touch and large screen (320 × 528 [as classPAD]). Can be NEWRPL currently is in the part of creation of the numerical engine and some of the symbolic https://sourceforge.net/projects/newrpl/

It's true that the FX5500 is very limited, but it was the first. The next CASIO with more capable symbolic manipulation was the CFX9970G from 1997.

RE: What was the 1st CAS pocket calculator?
The problem seems to be that there is no clear definition of "CAS". In this article from a previous HP website they claim the first CAS calculator for themselves:

HP 100LX with derive?

RE: What was the 1st CAS pocket calculator?
I used to use DERIVE on a SHARP PC3000 in 1992. Very nice at that time...

Derive was available on the HP 95LX in 1991: HP 95LX: Derive Maths Programme

RE: What was the 1st CAS pocket calculator?
It is necessary to investigate more on the hp28, to catalog it like the first CAS on a calculator, now the ROM of the DERIVE, is external, we speak of CAS embedded
The ROM still Helwett Packard has rights on the ROM?, I dream of seeing it ported in the hpprime, Why HP did not buy DERIVE and included in a calculator, did Texas get ahead of it? Texas also took the wrong decision to discontinue DERIVE, the version for calculators is not complete, just as the xCAS of hpprime is not synchronized or updated with the version of PC

Although not as powerful as Derive, it performed a lot of impressive symbolic math. It was featured in HPX Exchange V1 N2 (Mar/Apr 1987), page 14. If you want to play with it on your HP71, it is called "SYMBOLIX" on Swapdisk 11 which can be downloaded as a LIF disk image (".DAT" file) HERE. <0ɸ0> Joe

If you're only interested in number theory I recommend
http://www.mathematik.unimuenchen.de/~f...ribas.html Version 1.14 was the last that ran on the 200LX, I believe.

I'm a big CASIO fan (sorry, guys), so this is really interesting! BTW what it means CAS exactly? I wrote a little Periodic table for my CASIO fx850P and this program used VALF() function. The chemical symbols are stored in a vector M$() and the atomic weights in M(). The program cuts the chemical formula and substitued all chemical symbol with their atomic weight like this: "H2SO4" > "M(1)*2+M(16)+M(8)*4" and after on that string I used VALF(). This is a really simple manipulation of a chemical formula to mathematical formula. This is required to eliminate parts of the formula and generate another mathematical one. But not part of the ROM.

RE: What was the 1st CAS pocket calculator?
Thank you all for your input.
So, it seems that the original CASIO fx5500 with initial production in 1986 is the first ever pocket calculator able to do a very rudimentary "C.A.S." by offering just three symbolic manipulations (and a Solver):  Factoring  Expansion  Simplification It is time to start hunting down a CASIOfx5500 for my collection. Apparently this is not a easy find these days, as even TAS do not have recent record of sold items for this specific model. Jose Mesquita RadioMuseum.org member

RE: What was the 1st CAS pocket calculator?
Is there a Casio fx5500?
I've found Casio fx5500L & 5500LA, an example of the LA being currently on offer on ebay. Edit: OK, it exists.

LeDudu (Olivier Dumas) have got it already and published in his CASIO collectors site (see firsts posts above). Olivier even care to share the exclusive Casio fx5500 Owners Guide. Thank you, Olivier! Now, I'm searching the local auction sites in European countries. Spain, Greece among a few others are good candidates, me thinks. Jose Mesquita RadioMuseum.org member

RE: What was the 1st CAS pocket calculator?
The Casio fx5500 is a very attractive looking calculator  We'll see who finds one first.
