hp48gx vs Ti-89
Tyler G. Ham
similarities and differences between the two and which one you would prefer
over the other and why? I'm a high-school senior in a position to recieve a
powerful calc for use from now, through college, and in the real world. I
plan on going into some form of engineering or science (chem, phys, bio,
etc). Which calc do you think will serve me best in my future? Please
disregard price and ease of use of certain features (I'm #1 in my class, I'm
sure I can figure out how to do whatever I need to do on it without too much
trouble). I say this because I know the hp is rpn, which can be tough to
get used to for some people, but I don't want to let little things like that
keep me from getting the calc I need.
Thanks!!

The documentation is good and exhaustive: No need to buy Urroz books, like
with the 49G.
Ti 89 is faster and has a bigger screen. Total RAM & Flash are smaller than
in the 49G.
The TI 89 answers are simplified into "standard textbook look",
the 49G usually leaves something unsimplified or just looking different.
The TI 89 operates mostly as a "black-box" answering machine.

That's nothing compared to the EQW flexibility !!!
Everything is in favor of the 49G CAS software...buy the Urroz books and
enjoy!!!

it can take much, much longer : one fairly simple example I tried took over
5 minutes to run on the 89, and only 15 seconds on the 49 : I guess we can
thank Mr. Parisse for that kind of great performance...

"TAYLOR" in RPN? I haven't got it to work since the function is not documented

It's documented e.g. at
http://www.hp.com/calculators/techsupport/manuals/49g/english/aug/commands-e.pdf
under "TAYLR" (not TAYLOR):
Level 3: 'symb' (function to be expanded)
Level 2: 'global' (variable in which the expansion is done)
Level 1: n (Order of the polynomial)
Example: 'COS(X)' 'X' 6 TAYLR gives 1-X^2/2+X^4/24-X^6/720
Hope that helps,

For TAYLR, see AUG Volume 2, other commands, Commands T-Z.
These "other commands" aren't included in the printed AUG that I
received from HP; why not is a mystery to me. It's as if they intended
the 49G only for users experienced with the 48 series.

Thank you for the correction! I was too general.
There are several other operations where the HP 49G is faster.
One of the slowist things in my TI 89 is looping.

Huge hardware quality diff in 48 over 49 .
48 KB is better , display is glass , not plastic . KB has hinged
keys and they're molded ( not 49 ) . 49 will not take the
use / abuse .
Long ago HP made a 2x series . The salesman threw one
against the wall . I got the HP21 and many times demonstrated it's
concrete qualities ( dropped it from 36" to hard concrete ) .

The Display on the HP49 is made of the same material as the HP48, it just
adds a screen cover in top of that.
Otherwise it's made of glass
I will not bet on your last statement : "49 will not take the use / abuse".
In fact, internal testings shows that the HP49 is at least as strong as the
HP48, and in fact, the keyboard is more resistant on the long term (no loose
on feeling)

Mainly because i don't know how to do it on the gx. The GX is set up
for Engineering. It already has a library of equations, which is very
helpful. The GX also is set up to use plug-in card for more uses. The
Ti-89 does not. I am still learning how to use the gx but i think it is
a great calc. The cheapest price i have seen for the gx is at
www.wagonphoto.com I have seen it a little cheaper somewhere else but,
I don't remember. You might want to purchase a PC-HP cable. I bought
mine through an aution for a little cheaper, but a lot of hassle.
Overall, the gx is a better calculator. That is my opinion. Most
University's and College's will most likely be using the Ti.

Except for the plastic cover, it seems to be an improved display. Why
was that ugly block of plastic added? Does HP have to take a step
backward for every step it takes forward?

Long term? The 49G hasn't been made for all that long has it? Perhaps
you mean extrapolated from accelerated testing? I've seen too many
products come through all of the accelerated testing with flying
colors, but then fail miserably after a few years of actual use. I
wouldn't bet either way on the long term. From the first day I had this
49G, I've had problems with it occasionally missing my keystrokes, so I
can't confidently type ahead like I can with a 28 or 48; I have to
watch the display and wait and see whether it noticed the key press. If
a new 49G has this problem, how well will it work a decade from now? My
48SX doesn't require so hard a press as either the 48GX or 49G, but I
don't know whether this is the effect of time and use or it was
designed that way; in any case, I prefer the way it feels.

You'll get used to it, and the keys will lighten up. Use KEYTIME->

Yes, I'm getting used to it, but that doesn't mean that I'll ever learn
to like it.
> Use KEYTIME-> and ->KEYTIME to adjust the key response.
Thanks Steen, good suggestion. I did that a few months ago and it does
help with the 49G responding to repeated presses of the same key, but
it still occasionally misses a keystroke. Or maybe it's just my
imagination, but I don't have this problem with the 48.

For an average high school student who carry its calculator in a bag full of
heavy book, it's more than useful... Not everybody take care of their

Regarding the keyboard, the HP49, just as any high-end Hi-Fi or speakers,
needs to be break-in. Takes a month or two :)
Will you criticize a Mark-Levinson amplifier because it sounds really good
after 1 month of usage ?

Agreed. How many posts have there been to the newsgroup beginning: "I have a
perfectly good 48G but the LCD is cracked. Can I get a replacement/repair etc."
I would think the new 49G plastic or glass or
enviro-friendly-clear-hard-substance (whatever) can be pretty easily replaced.

Perhaps some sort of hard protective case, padded on the inside, would
work as well? But of course, we can't rely on a high-school student to
put his expensive calculator back into a case. I wonder how well it
stands up to pizza sauce and pop spills; maybe the whole thing should
be covered with some sort of protective latex membrane.

Actually, the force required for a key press is, at worst, a very minor
annoyance to me. I didn't mean to complain about that.

I'm not familiar with that brand name, but if it inexplicably dropped
the signal every now and then, then it would go back to the store in a
hurry.

One who has a 49 will more likely lie about it's features so he can

and would be the best source of advice on 49 purchase .
I vote the 49 to be crap .

No matter how good or bad a particular product is, there will always
be some people who like it and some who don't. Those who don't like
it are far more likely to sell it or get rid of it. If you depend
only on the opinions of those who have sold it or gotten rid of it,
you will bias the result towards the negative.
FWIW, I have had no trouble with my keyboard. And, no, I'm not
selling it.

Surely, though, the slip-on shell addresses this concern. (Perhaps
there should have been an adult version of the HP49G, for those of us
who know how to take care of a valuable work of art such as an HP. :) )

I'm afraid it takes a good deal longer than that; mine has seen almost
daily use for 11 months and the keyboard still requires MUCH more care
(and consequently more time) than those on my 32SII and 48G+. Without
exaggeration, I can work about twice as fast on the older keyboards.
It's quite maddening: brilliantly-written software (much better
thought-out than most PC software, with the sort of attention to detail
that makes engineers absolutely glow with pleasure), but then you cram
it into the most appalling blue box, with a keyboard and display cover
that seem to say "just try and get past me -- you'll never take
advantage of MY brain!". (You can pull the display cover off easily
enough, but the keyboard problem seems a bit more difficult for the
end-user to address.)

One would think, but they still wouldn't sell me one the last time I
asked. The only way to get a new one was to send them your calculator
(with a damaged cover) and they would replace it under warranty. Which
is rather useless to those of us who took the bloody thing off because
we couldn't read the display (thereby voiding the warranty, it turns out
-- not otherwise a huge concern, since HPs seem to last more or less
forever).

I have a 49G, ID9310..., and it never failed. I use it for
programming, text, graphics, math, etc. I upgraded the ROM as many
times as a new ROM has been released. The serial port NEVER failed.
May be because I have only original hardware (Cable). No patches. The
cable can be used for both the 48 and 49(it is for the 48) with the
adaptors it has.
The keyboard isn`t as good as the 48`s, but it isn`t bad. I only
dislike the screen cover`s scratches.
I like my 49G over my 48 (speed, memory and software) and I am very
proud of the 49G (also 48). I was the first on my school who had it.
Just my opinion.

Hey Tyler!
Pay no mind to the huge partial comments made in this NG about the
calculators, specially the 49G.
The facts are that... you want a state of the art calcomputer right?
small enough to fit in your pocket but powerfull enough to calculate the
size of your.................. whatever in a microsecond! right?
I would ask you this:
Are you going to pee, shit, step, jump, dump or otherwise pounce on it
regularly?
Are you the sort of guy who likes to place sophisticated electronic
instruments in body cavities too tight for this purpose?
And, once you choose to take it out whatever hole you stuck it into, are
you gonna try to calculate the largest prime number in your life time
using only this little bitty calculator ?
Are you going to soak your hands in bleach before you handle the calculator?
Do you get sick pleasure from dropping expensive electronic gadgets from
the top of tall buildings?
Are you going to try and use the calculator as a diving computer on your
next vacation to the Bahamas?
When you get a new toy, the first thing you do is reach for and actually
read the f$%@&ing manual?
Do you hate snobbish french (redundant I know) egg heads?
Are you a knit picking SOB who's never satisfied with anything,
specially if you had no say in its conception, design and/or construction?
If you answer NO to all the questions above, by all means get a HP49G,
you will be only slightly desappointed and will have lots of fun
guessing whether the CAS if actually giving you the right answer or its
just showing its neurotic genealogy by pissing you off, the french way!
Just kidding :) HP49G rules the world!

I think HP should hire you to their marketing department, the sales

calc too, and I personally have had no troubles with the keyboard
whatsoever. I don't see how you can say that the keyboard is faulty, I
think it is just a change that some people like or don't like. I have had
no troubles with mine, no serial port problems, and I like it a lot better
than my old 48g+, mainly because of speed and the large memory. So next
time you start to bash the 49, realize that there are many satisfied users
out there, maybe just not you.news:t7tshjd...@corp.supernews.com...
