The HP-48 is my favourite calculator.

It can do matrix math, vector math, complex number math 
symbolic algebra math, deriving, (some integration),
numerical solving of equations and much more.

It is VERY programmable, has TONS of functions and 
there is very much stuff on the internet for/about it
(and it's relatives). E.g. the comp.sys.hp48 news group.

You can download the emulator for it from this site:

http://www.hpcalc.org/hp48/pc/emulators/
(The emulator is called "Emu48 1.20")

You should also download the latest service pack for the
emulator (which can be downloaded from the same web page);
"Emu48 Unofficial Service Pack 22"

And you will also need a ROM-dump to run on the emulator;
e.g.: "HP 48GX Revision R ROM" (that also is available at
the same web-page.) The zip-file contains a file that has 
to be converted like this:

convert gxrom-r ROM48.G

(The convert program is found within the zip-file for 
the emulator.)


Here's the FAQ for the calculator:
http://www.hpcalc.org/hp48/docs/faq/48faq.html


http://www.hpcalc.org
doesn't seem to be controlled by Hewlett-Packard.

Blasphemy!

Sounds like the TI-89, but, according to my dad TI calculators are less
well constructed.

I couldn't help but notice 6.1 in the FAQ though:

Then enlighten me !

When the HP-48 arrived several years ago there
simply were no competitioners. No other handheld
calculators at that time did even come close to 
what it could do.

But I haven't watched the evolving of other
calculators lately, so I'm not quite sure about 
the situation right now.

Yes, I have heard that noise from some other HP-48s,
BUT NOT FROM MINE !


One interesting thing is that someone announced
that in addition to programming in RPL and Assembly, 
it is now also possible to program it in C.

I think it also is possible to insert memory cards
into it with 1 MB or more with battery backed RAM.

And the HP-49 seems to have built in FLASH for its 
firmware.

Right now I'm investigating the possibility to use 
a terminal emulation program (VT52bis) running on my 
HP-48 to log into servers through my Siemens C35i 
mobile telephone (which has a built in ISDN/Analog 
modem.)


And the HP48's IR-port can even be used for remote 
control of TVs, HiFi equipment, etc.

The 48 sounds pretty much the same as the 89.

The 89 has the old carbon contact buttons with the rubber sheet. Those wear
out after many years, fixing an old-skool Nintendo controller the rubber
sheet was practically shredded. Stuff like that.

10Mhz Motorola 68000. :D

The 89 does symbolic calculation, derivation and integration (symbolically),
FLASH ROM for the upgradeable ROM and for the archive memory, where you can
store variables and stuff that don't get edited, like most asm games. It's
got 188k user-available RAM and 384k FLASHROM. Nice high-res display,
160x100. Everything is displayed as it would be written in a textbook. It has
tons of functions, like complex zeroes, taylor series, limit, sigma including
to infinity, product including to infinity, 3D graphing. The algebraic solver
can take any number of entries compounded by 'and', like 'y=2x^4+5 and y=5x
and x>2', and it can return expressions if the solution isn't a number. And
of course differential equation graphing and all that. I don't think RAM is
upgradeable, but there are 3rd party RAM expansions that use the link port.

There is now a freeware 3rd party gcc compiler for it too. Woohoo!

  Does this mean that it would be possible to compile the plain ascii version
of povray to it?

It'd take a lot of modification since TIs don't have floating point. You have to
use a struct ti_float (bcd) and special functions to do all the math.

  If gcc is ported in the right way, then the compiler would handle all
that automatically.
  For example, you can perfectly compile povray for a 386/486 with no FPU.
It will be slower, of course, but it will run.

It's a pity that they use this solution !

Some 8 years ago I had to buy several spare rubber 
sheets for my ZX Spectrum.

=)

Cool ! I like those.

This may be a good reason for me to have a closer look 
at the TI-89.

Maybe I could make some interesting electronic add-on-
gizmos for it.

Is it possible to access the uProcessor bus from the 
outside of the calculator ?

Sounds promising !

Are there any emulators for it ?

Yeah, stupid rubber sheets. And the 89 is a lot harder to take apart than the other
8x's because it has hex-wrench screws.

I don't know. You can do a lot of stuff through the linkport, but I'm not sure
what.

Might wanna try ti89.acz.org

Not far from the Mac Plus I have in the basement... :-)
Higher resolution screen, more memory, nicer OS, but a bit bulkier...oh, 
and the Mac Plus has an '030 upgrade. ;-)
