HP 28S  Partial CAS?

HP 28S  Partial CAS?  mrscorpio  06042011 I've recently become the proud owner of a mint HP 48GX
However this has gotten me into researching other HP calcs etc.
My question is, the 48 series came out shortly after the 28S & dominated the 90's, but WHY did HP 'Drop' the seemingly Useful 'CAS' features that the older/simpler 28S had?  With HP calcs not getting CAS again until the more current models.

Re: HP 28S  Partial CAS?  mrscorpio  06042011 So to clarify: Re: HP 28S  Partial CAS?  fhub  06042011 Quote:Don't ask me about any details, because I've not used it since many years. IMHO any 'CAS' on HPcalculators is not a CAS bust just a nightmare. If you want to use a serious CAS on a handheld then there's only one choice: TI92Plus or TIVoyage200 (although I prefer the 92 because of its much better keyboard). Re: HP 28S  Partial CAS?

I desagree. The 49 & 50G CAS is OK.
Re: HP 28S  Partial CAS?  Jeroen Van Nieuwenhove  06042011 The HP 48G series have the same ISOL, EXPAN and COLCT commands as the HP 28 series. At the time of the introduction of the HP 28, that was quite a feat, but it is of course nothing compared to the possibilities offered by Erable and ALG48 (or any modern CAS).

Re: HP 28S  Partial CAS?  mrscorpio  06052011 Interesting that you mention that.
Would it be fair to say then that even though the 48G series 'isn't' touted as having CAS, it 'does' have numerous 'CASlike' capabilities? Edited: 5 June 2011, 5:06 a.m.
Re: HP 28S  Partial CAS?  mrscorpio  06052011 I've yet to get a serial cable for my 48GX, but when i do....
It is possible to get both Erable AND ALG48 on the 48GX at the SAME time?  How much free memory is left when one or both are installed? Re: HP 28S  Partial CAS?  Jeroen Van Nieuwenhove  06052011 ALG48 and Erable share a lot of functionality; in fact Erable is in part derived from ALG48. Head over to hpcalc.org and read the Erable and ALG48 documentation to find out more about the differences (specifically section 3.3 of the Erable documentation). Main point is: if you can have the two of them on your HP 48, do not hesitate.
Re: HP 28S  Partial CAS?  Jeroen Van Nieuwenhove  06052011 Well, I only own a physical HP 48G, so I do not have any experience. I stuffed Metakernel, ALG48 and Erable into my Emu48 emulation, but I do not know which memory card you need to accomodate ALG48 and Erable on your HP 48GX. Re: HP 28S  Partial CAS?  mrscorpio  06052011 Many thanks for the responses. Re: HP 28S  Partial CAS?  Jeroen Van Nieuwenhove  06052011 I guess the reason why ALG48 and Erable are mentioned together so often is because these two applications were integrated in the later HP 49 and 50 series. CAS48 and its manual can be found under the link I posted earlier. I have no experience with this application, but the documentation contains a list of its CAS functionality. You also might want to post your questions on comp.sys.hp48, which is a more specialized forum for this.
