From what I've seen, the TI-89/92 is more for out-of-the-box use. The
HP-48/49 requires a bit more work to figure out, but is more powerful for
the most part. Sorta like comparing Windows to Linux.

I would buy the HP-49 over the TI-89, but I would buy the TI-89 over the
HP-48. Here's why. (All price figures are approximate, and in US$.)
I'll first say why I rule out the HP-48. It is worse than the other two in
EVERY respect except for the following:
-It costs around $40 less than the TI, and $60 less than the HP-49.
-It has a built-in equation library.
-Its keyboard has the best feel.
That's it. So unless you have a tight budget, don't get the HP-48.
Now the decision comes between the TI-89 and the HP-49. The TI is worse than
the HP in every respect except for the following:
-It costs about $20 less, even taking into account that HP sends you a free
PC-link cable if you call them and ask for it.
-It has a more comfortable keyboard; the HP's is kind of stiff. But I got used
to the HP without getting carpal tunnel syndrome.
-It has a better screen--easier to read, and higher resolution. You can improve
the HP's screen visibility by yanking the plastic screen cover off or cutting a
square out in the middle, but that makes it look uglier and voids the warranty.
-It has a faster processor--10 MHz, as opposed to the HP's 4 MHz. HOWEVER, the
HP is comparable in speed; it has a slower-responding user interface, but it
does calculations just as fast, if not often faster. The reason is that HP has
better engineers and programmers constantly working on making the operating
system more efficient. They release new ROM updates every month or so, which
you can download and send to your calculator.
To sum up the HP's advantages: it has far more functions, twice as much memory
(over 1 MB), and much better support (this newsgroup, for example).
TI's are kind of like Macintoshes: they have superior hardware (supposedly) and
are easy to use, but the sofware and user base are no good.
Am I leaving anything out, or getting something wrong? (I purposely didn't
mention RPN because that is a matter of personal preference.)
Anyway, I hope that helps.

I think he's referring to programming support.

was having problems programming my CBL and the TI guy spent over an hour on

If I had been a teacher or Admin, I would have probably expected that level
of support. But for me, a normal (close to straight A, though) student,
TI's support meant a lot. It also meant that I got an A+ on my project,

I bought my HP48G+ to replace an ailing HP-67 that ran like a champ for 22
years. What I really wanted was my HP-67 to rise from the dead, and I was
prepared not to like the new machine, but I think it's a champ. The two
best reasons to buy HP over TI are RPN and good experience with previous
HP machinery. The machine also has a pretty good display, uses regular
batteries and addresses a broad range of engineering math, including units
conversion problems. Graphing on a window the size of a business card
doesn't seem all that useful, but it's there (I have a better graphing
calculator on my Mac). it'll do elementary calculaus and differential
equations, which I think is very cool, but not something I do every day.
Whichever one you buy, you'll probably make daily use of a fairly small
fraction of the total capability, anyway.
The bottom line is to ask yourself what you're going to do with it. If
you're going to push the envelope and squueze every drop out of the
machine with every task you do, spend the extra bucks and get the HP-49.
OTOH, if you have a computer to do your big arithmetic, there's no reason
to beat yourself bloody with elegant programming capability on the HP if
you have a spreadsheet or a compiler for your computer. I g my HP-48+
because I need something to stick in my briefcase when I go on inspections
or do some quick back-up calculations for a stress analysis. It's perfect.
And TI's are nothing like Macs. I've been a Machead almost as long as I've
had my own engineering practice--just over half the time I owned my HP-67.
The MacOS is better designed, more stable and makes for more productive
use (like RPN). I do mechanical analysis on my Mac and software has never
been an issue. Yes, there are more programs for Wintel iron, although not
that many more when you sort the crap from the Wintel listing. (And how
many different games, text editors, screen savers and disk recovery
utilities do you need anyway?)

And by not mentioning RPN, you've left out the single most important
reason to prefer nearly any HP calculator over nearly any TI (or Casio,
or anything else). The other things you mentioned (keyboard, screen
size, memory, etc.) are matters of personal preference, too.
Personally, I would choose the HP48 over the 49, mainly because of its
superior hardware construction. It's also closer to the pinnacle of HP
calculator design, the HP-41/42 family. In fact, for anyone who doesn't
need a graphing calculator, I'd recommend a used HP-41 over any of HP's
current offerings.

I think the difference is that TI is good at support for standard users and
HP also helps out programmers.
Jason Katz-Brown
Yes, I agree with Veli-Pekka. I had the same dilemma over which calc to
buy, and I chose the 49. I love the customability, complexity, and
vastness of the software and OS and hardware. In spite of its few "fit
and finish" issues, I don't care a bit. Oh, and I LOVE RPN.
Veli-Pekka, how does one use STARTEQW?? I don't want to miss out on a

I used to like my TI-83 plus, but then its link port somehow doesn't
work (and tic...@ti.com didn't help) and I saw an HP, so I never use
it. After using my 82 for a week, it looks silly (hehehe).
I really like my trusty TI-82, however. Even though it has the _worst_
screen in the world, it is 6 years old! (My brother used it in high
school, and in college doesn't need so he gave it to me.) The keys are
great (better than 83+), and BASIC is good for little programming
projects (like my RPN prog), and with RPL those two languages can do
anything (BASIC is waay limited).
But I love my 49. It is everything I want, so I am asking for nothing
more (and why I am never going to a TI newsgroup again).
So, I dunno, get want you want.

Obviously any companys support depends on the country,

I agree that the HP48 is an excellent calculator (I own one myself), but
it is inferior to the HP49 because it is RIDICULOUSLY slow. The HP49's OS
has been rewritten to be much faster. I can't stand waiting for the 48's
cursor to move when I press an arrow key, or for the PLOT input form to
come when I call it up.
However, I still feel nostalgic about the 48's perfect keys, convenient
keyboard layout, and well-exposed screen. True, the 48's casing and
hardware is better, but the software is too inefficient.

Well, that's why I said that other things besides RPN were a matter of
personal preference. Speed is FAR less important to me than a decent
keyboard and screen. Besides, I find the 49's exterior design and
colors so repulsive that I'd be intensely embarrassed to be seen in
public with one. I know the excellent software should outweigh the
appearance (and if I really needed the 49's advanced capabilities maybe
it would); but the 49's "look" is so deeply offensive to me that I just
can't get past it.
Jason Katz-Brown
Hello!
You shall get the award for longest poster.
Where did you find an HP logo?
Also, whenever you stokeys, all the gokey dependent ones are messed up!!
Is there a way around this??
I have an infinite number of questions about that stuff, and the darn UG
or AUG can't answer. Oh well.
Okay... So if I type in all of that, I will have a Velicalc? Some of it
wouldn't really work right. If I type in the program, let us say ERRBEEP
and STARTERR, then store the STARTERR program to the global var STARTERR
(and same with ERRBEEP), will my error beeps sound different?? Mine
didn't.
Also, the ->contrast went right over my head.
I'm confused.
I have fallen into the dark abyss of infinite HP customability. I had
been happy with user keys, but now... help!
Do you like editing with a small font? ick. Why would that have to be in
STARTED? Shouldn't that just be set in stone in sysflags??
Thanks,
Jason (who is almost done with full version of RPN828383+)

Nicholas A. Gallegos
1) Do you like RPN (reverse Polish notation)?
2) How memory do you need?
The HP48G+ is merely a 48G with 4 times the memory (128k versus 32k). The
TI-89 is generally a faster calculator (faster processor) and it offers more
in terms of features and future upgradability (due to its CAS and upgradable
flash memory). The calculator you really should be comparing the TI-89 to
is the 49G. That's a fair comparison.
- Nick
Jean-Yves Avenard
It's a great datalogger, and is compatible with all the Verner's probe (just
like the TI's CBL).
It's also compatible with TI's CBR
It has two built-in probes (sonic and light)

thought one of the HP's weak points was that TI had the CBL and the
probes that could be hooked up to it, and the HPs didn't. I see now
that isn't the case :)

Spam filters in place. If you are accidently blocked, remove nospam.
Mitch Richling
So it would seem that the real weak point HP has is that
teachers don't know about this thing and have no help using
it. This is a better data collector, judging from the add,
than the CBL, but no one is going to use it in classrooms till
educators know about it AND it is easy to get started using it.

So what's that little thingy at the bottom of the screen you type

I think he meant that mainly as a humorous remark, but also the HP48
command line goes farther (as you emphasized): it's made to allow
execution of programs or any kind of command, whereas the TI-89's command
line is aimed at entering mathematical expression (and it's pretty hard to
enter matrices on one line - even the HP48 without mtrw is better on this
regard). I think it's possible to put programs in a TI's command line, but
it requires the insertion of line delimiters, etc.
The comparison looks fair, calling command line what the TIs have is like
calling command line the "Execute" box of Windows.

I've been playing with a TI89 quite a lot for the last week. I've
never taken the time to look at them before because I was so happy
with HP.
I almost always enter matrixes on the command line in my 48. For a
3x3 it takes 21 key strokes with CLI on a 48, 22 with mtrw on a 48, 23
with CLI on a TI89, and too many to count with the matrix writer on
the TI89.
I like the HP better because this works: [[1 2 3]4 5 6 7 8 9].
Best I can figure out on a TI is: [1,2,3;4,5,6;7,8,9].
The TI CLI would be much better if it could figure out where to
put , and ; based on the first placement. It would also be MUCH
better if it put in the last )'s for you. Now would that be so
hard?

It looks like you can put most anything on the command line and have
it work. It's just tricky to know HOW to put in so that it works.

I think HP to TI is more like comparing a UNIX tcsh/bash shell to
a MS-DOG command prompt or a Macintosh MPW prompt.

HP49 ~ $180 and cable is free for the asking. Keys are stiff
compared to other calcs; screen cover needs to be modified
and the port needs to be plugged when not in use. The
documentation is lousy (but the User Group is outstanding).
The HP49 is hard to use; if you haven't used an HP48 prior
to the 49, the learning curve is incredibly steep, although
the latest alpha CAS has built in HELP for commands. One of
the high points of the 49 is the flash upgrade - the CAS is
being improved continually. The CAS reportedly has more math
capability than the TI CAS but the majority of users would
never see it, IMO. One place the 49 shines is flexibility
and configurability: reassign keys as you choose; write your
own startup programs; RPN or algebraic input; BASIC,
UserRPL, SysRPL or assembly languages. The 49 is slower than
the TI-89/92+ in many areas: user interface, most routine
graphing, Calculus I and II level integration and
differentiation, many common math functions.
Either one will do more than you need to get through
college. If you have time to learn it, the 49 is a very
powerful tool. The 89/92+ is faster, much easier to learn
and also a powerful tool. Nothing else in a calculator comes
close to either of these two incredible machines.
I recommend getting both.

TI-89. The HP-49 is a good calc, I'm sure (I've never used one), and much
less ugly than previous HPs (not that it matters for a calc), but from my
experience TIs are much easier to use and extremely capable machines. The
89's hardware beats the 49's in most areas, but the 49 has some better
software features, as I understand it. Anyway, I don't know how I got by all
those years without my TI-89. It's an awesome calc.

RPL = Reverse Polish Lisp; UserRPL is akin to BASIC; SysRPL
is much lower level (closer to the system), no error
checking, much faster, harder to learn. I think I heard that
DERIVE was written in LISP.
Check here for what's available for the 48; I would think
soon for the 49.
http://hpcalc.org/pc/programming/
Most do SysRPL, though.
hpcalc also has emulator, ROM, and docs for 49.

Actually a steep learning curve means the calculator is *EASY* to learn. A
learning curve plots % mastery on the dependent axis (Y) and time on the
independent axis (X). The steeper the curve, the shorter the time it takes
to learn a given subject and the easier it is to master. A shallow curve,
on the other hand show the material is tough to learn and takes more time to
fully understand.

"Many people use the phrase "steep learning curve" to refer
to something that is difficult to learn. This makes sense if
one thinks of plotting amount to be learned vs. time."
A Google search on "steep learning curve" will produce
hundreds of examples with meaning similar to mine.
The implication of "steep" being "hard to climb" and
"needing to expend much energy to achieve" reinforces (to
me) the concept of "hard to learn". I didn't realize that
some would not understand this; thank you for bringing it to
my attention.

IMO the difference is that the 89 is easier to use but the 49 is more
powerful (except the CAS IMO). One good example (a bit simple tho) is that
the 49 has an OFF command to turn off the calc - you need to use ASM to turn
the 89 off in a program.

It's a bit more than the 89. Even after you include the free computer link.

BTW the 49 also has HP-BASIC, similar to TI-BASIC (but RPL is faster).

RPL, RPN and the user interface are what makes the HP48 great and to
a lesser extent the HP49. But if we just consider "functions"....
One thing that is very important to me is that the TI89 can't touch
the HP's matrix handling capability. The 49 adds symbolic
matrixes(something I had to implement myself in the 48), but I'm
talking about the numeric stuff. In fact, when I bought the 48GX I got
it because of the improved matrix operations from the 48SX. It
did condition numbers! Wow! The symbolic stuff is nice, but the
numeric operations are what pays the bills. :)
Also the binary number support is MUCH better with the HP. But
not better than that famous old "computer scientist's calc". I
think the HP16.

I, too, prefer editing in the small font - but if you set the flag,

If it executes OFF then no

What about normal PCMCIA-Card-Slots?
And, in addition to that, a fine, comfortable Developement Environment

O.k. here's a slight twist on the subject: I have had a HP32SII for
about 8 yrs now, and love it. Fast, RPN, and just does everything I
need on a daily basis, w/ room to spare. It got my tail thru Math,
Physics, Reactor Principles, and Heat Transfer & Fluid Flow in Naval
Nuclear Power School (for those who care the above courses roughly
equal Applied Trig/PreCalc, Nuc Physics, Reactor Kinetics, and
Thermodynamics), so I am a little sentimental towards the old 32SII.
Now I am gearing up to go back to school to get a degree (gotta have
that paper ;), and am probably going to be enduring Calc & Physics I,
II, & III. I have been told that I will _need_ a graphing calculator,
and a friend has offered a HP48GX that he just doesn't need anymore...
He does his engineering stuff on a 'puter. My impression of the 48GX,
compared to a 32SII at least, is sssllllloooooowwwwwww!!! I'd like to
get a Meta Kernel ROM, as that supposedly increases the speed
drastically, but I haven't been able to find a supplier whose web page
actually works. I don't want/intend to play games, or try to control
my t.v. or all the other little things you can do w/ a 48GX. I just
want to get thru math/physics/comp sci classes w/ a minimum of hassle.
And I _prefer_ RPN. Is it worth the time and money to hunt down a Meta
kernel ROM and possibly a 1 MB RAM card for the 48GX, or should I cough
up the dough for a 49G, or is there another _decent_ calculator that
does RPN?

I bought an MK card for my son from BB Marketing a few months ago, and
as you said, it's version 2.2. There's a review of 2.3 on the hpcalc
web site that says "... few changes have been made since the 2.20
release of the ROM card." If you want to read the whole review, it's at
http://hpcalc.org/apps/mk/mk.html but keep in mind that the references
to version 3.0 are out of date. Now that the 49G is here, I don't
expect ever to see 3.0 (or any later version) for the 48GX.

The HP-49 is way slower that the TI-89's in integration, graphing, or just
navigating through windows. However, I like the fail-safe RPN entry where I
can't make a mistake with parenthesis or anything like that. I really like
my HP-49, but the truth is that it caused me some head-aches as performing
tasks such as just changing windows would take too long. Also, solving for a
variable in certain equations are a pain sometimes due to the infamous
"non-rational expression" (something like that) error message. The TI's
could do these same equations in a heartbeat (and since you're so concerned
with speed, the TI-89 is worth looking into as it can perform much of the
required tasks in those kind of classes rather expeditiously).
Since you're a fan of RPN, I could recommend the HP-49G as one of the best
RPN calculators out there (some people like HP-48GX, but I've never used one
so I can't say anything about it). However, it would be unfair to say that
it is undisputedly the best graphing calculator out there. The TI-89 is
great for physics and calculus classes especially with the superior teacher
support (although it is an algebraic only calculator).
Hope this helps!
Just my two cents,
JC
P.S. Get your hands on some emulators so you can get an idea of how each
calculator is like.

the HP-49 the TI mostly just stays in my book bag. I have found that
the TI-89 is good at what it does, that is general text book calculus
and returns the answers quickly provided you have not placed a
parenthesis in the wrong place. It has proven to be almost useless in
my electrical engineering studies.
The HP-49 has a lot of the functions I need already built into it,
Curl, Divergence, Laplace Transform, Partial Fraction Expansion and
others. It is a lot easier to program and it implements the programs a
lot faster. My two cents worth, if you want a calculator just to get
you through calculus, then go with the TI-89, but if you want a
calculator which you will find usefull during and after calculus get
the HP-49. You can't beat the Equation Writer and overall
functionality of an HP.
By-the-way, at the University I attend HP's far out number TI's in
the School of Engineering, my best guess is because a lot of the needed
functions and formulas are already built into the HP's and the
engineering support base is larger.
