====This is just a whine, but I wanted to get it off my chest
to otherswho know what Iım talking about. I was very happy to
snap up a 49G+almost as soon as it was available. But I was
dismayed that not everykeystroke registered--I mean, this is
an HP calculator, not a toy! Buteven worse, it soon crashed
while running a simple program. I use thefollowing program to
turn off my calculator, so that when I turn it onagain it
tells me how long itıs been since I used it: (RPN mode)ZZZ<<
<<OFF>> TMIT>>TMIT<< TICKS -> x << EVAL TICKS x - B->R 8192 /
1_s * DUP 0_d + >After executing ZZZ a few times the
calculator wouldnıt wake up, itjust ŝashed when I pushed the
ON key and immediately turned offagain. After pushing ON
rapidly a few times the display came on, butthe calculator
was unresponsive to keystrokes, and the busyannunciator was
continually on. Eventually I took out the batteries,and it
recovered its sanity, though not its memory.I donıt regard
crashing as acceptable behavior in a calculator. Iexchanged
it for another 49G+. Same problems: a few ŝaky keys, and
iteventually crashed the same way while running ZZZ. So I
returned itfor a refund.I donıt expect HP calculators to
misbehave. Clearly, this model hassome teething problems, and
they are serious enough to put off thislong-time HP owner. Ah,
well, back to the old 48SX.Alan WeissMillburn, NJ====X>

working in Costa Rica, Centralamerica, and I am concern about
theability of HP49G+ to support our tropical climate, over 32C

means that lots of humidity will condense inside the

live in Costa Rica too and have had no problems so far with
myhp49g+.of course I have had not enough time to evaluate the
calc on variousconditions because it was stolen along with my
backpack. Now Iımwaiting for my second unit to come out of
the Customs OfŜce.I do not know of any plugs you could use,
for the sd card slot, if youdo nothave the card itself
inserted, you could use a dummy card (like theones that come
with the palm devices), they retail for $1
atwww.gethightech.com for instance.I think there is not much
chance of protection from our climate here.if you were to
cover the sd slot and the usb plug you will still beleft with
all thegaps that exist between the plastic keys and the
calculator body !Years ago I bought a protective case from
Tripod Data Systems for my48GX, it is transparent on the
front and kind of neon orange on theback and allows to
operate the calc from within the case. I found itvery
practical while I was doing some surveying work at
GuayaboNational Park. It was protected from the rain and it
was visibleanywhere I forgot it too! so it was never hard to
Ŝnd it. I do notknow if they still have this case though,

my problem, itıs for G+, but might work on G aswellGood
luck!Just in case it isnıt obvious, please be aware that it
takes a fasthand to do this correctly. You have to press and
hold down thebackspace key IMMEDIATELY, the very moment that
the warmstart begins.This is much more difŜcult to do on a
49g+ than it is on a 49G.If you can force a warmstart by
pressing ON+C, then do it this way:Press ON and hold it down,
then press and release the C key (whilestill holding down the
ON key), then SIMULTANEOUSLY release the ON keyand press &
hold the backspace key. Sounds complicated but it ainıt.If
Try To Revover Memory? is displayed, then take a deep
breath,then press and release NO and IMMEDIATELY press & hold
the backspacekey. This oneıs the most difŜcult; there can be
no more than ONEPRECISE INSTANT between pressing the NO key
and pressing the backspacekey. A fraction of an instant is
even better but is not required.If the crash is so bad that
none of the above work, then perform apaperclip reset with
the backspace key held down, which will force thereset to
pause midway with the screen turned on but blank. To
resumethe reset and bypass your libraries, momentarily
release the backspacekey and immediately press & hold it
again. Momentarily means ofduration greater than zero time
and less than or equal to one preciseinstant.If the paperclip
reset doesnıt work, you can fake it into thinkingthat youıre
going to update the ROM without actually doing so. Hereıshow
to do that: Press and hold BOTH the + key and the - key
whileperforming a paperclip reset. You will see the screen
turn on butremain blank. Release the + and - keys. You will
see the ROM Updatemenu (1:Update Code, 2: Self Test, 3:Secret

the same one ordinarilyobtained by pressing ON+F). Now take a
deep breath, press and releaseON and IMMEDIATELY press and
hold the backspace key. This will forcethe reset to pause
midway with the screen turned on but blank. Toresume the
reset and bypass your libraries, momentarily release

just got my HP49G+ a couple of days ago. I agree with your
assessment.I had the same problems with Win98. Itıs probably
a USB problem. Win98 is not a good USB OS. You can get
patches from Microsoft. My Win98 installation has been
patched. HP has an upgrade to their USB drivers and and
connect program available on the net (you probably already
know this).I tried to connect in Win98 using both the
original and the upgraded USB drivers and Connect program.I
got it to connect and ŝash the rom without any problems,
however this uses a different protocol (I think). The
interactive connection, using the xmodem server on the 49G+,
is more problematic. I got it to work several times, almost
without rhyme or reason. I havenıt experimented enough yet,
but I think the solution may be the order in which you start
the calculator server and make the connection. The version of
USB driver or program didnıt seem to make any difference.The
noise is worst on the lower keyboard. Itıs much less up near
the screen. You can eliminate much of the noise if you press
the case against the table when pressing a key. I think
thereıs some kind of loose wire or other very light object
that buzzes slightly against the case. Maybe itıs the
keyplate? I donıt have the courage to try it, but maybe a
little superglue under the faceplate would help. I would
dearly love to open this little gem up and see what may be
loose.One thing that is missing from the 48G is the optional
key template that sets on the faceplate.I like the keyboard.
Itıs stiffer than I would like, but Iım so happy to get away
from the mushy 49G keys. I spent some time comparing them to
my 48G. Theyıre quite similar in terms of quality and
positive feel, just stiffer. Theyıre not all black. The upper
function keys are slightly translucent.The gold faceplate
originally turned me off. I discovered, however, when sitting
in bed late at night and trying to operate the calculator,
that low light visibility is quite good. The faceplate gives
a very good contrast with the keys, and the lettering on the
faceplate shows up quite well. Certainly better than the
49G.The case is more rigid than either my 48G or 49G. The
older HPs will squeak if you twist the case a little. This
case doesnıt make a sound.The weight is much improved. The
49G was too heavy for comfort.I did Ŝnd a couple of new
functions. It does Laplace and Fourier transforms. Not that
it matters for me at this time!My impression is that the 49G+
is not cheap.EricI got my hp49g+ two days ago.> I bring you my

Matthew MastracciI know that the 49g+ is faster, but not that
fast:Think about it as 64MB/1MB card or 256MB/4MB card(I mean
MMC/HP memory card or SD/Epson or Klotz or...)If we think the
49g+ to be even 8 times faster than 48G* JYA * can you help
with these Ŝgures, please?then it would still be 8 times
slower to start.The libraries must be scanned at least once
at the startbut the 48GX system does it at every power ON(to
be sure that the card was not replaced by another one)Even
now when the Type of the Ŝles are read (unnessessarely IMO)it
takes (too) long time to scan an SD card on a 49g+Maybe an
explicite ATTACH (or a short UserRPL macro)for port 3 library
with build-in attach-only-oncecould do the trick, but 768KB
Flash is currently enough for me.(Iıd rather take a hp 49gII+
with 2M+2M port 2 & real serial)====Make sure you install all
the libraries in the package in Joseıs link... well, maybe
eTools is not necessary... and install them to port 2. I
think it says that in the readme. Then either turn the calc
off, then on ~OR~ do a warmboot- on and F3 simultaneously.
The libraries should be then installed, ready for action,

--------------------------------------By setting ŝag -33
(Transfer via IR) and ŝag -34 (Print Via Wire), I was able to
send the output of all the print commands to a DeskJet 990Cxi.
There were some font mismatches, but the general expected
format is there. I was unsuccessful with ŝag -34 cleared, so,
it seems that, although both send via IR, ŝag -34 cleared
sends at a much slower baud rate (as noticed by the hourglass
indicator being on much longer). I assume less than 9600,
which is the minimum IrDA baud rate. Toby====> By setting ŝag

have a weird behaviour, only shared in the previous
SaturnROMs by the RTN** instructions and C=RSTK:trying to
yield a beepinside a program withoutusing the GOSBVL makebeep
entry,Iıve written a program thatincludes makebeepıs

01630 ends with a return instruction)And it provoked no

where the ROM iscalling the routine from.SAVELC 00140%

govlng goes to#3FEF1 then returns to 1626, which jumps to
#1630, and then returns tomy program (Œreturnı label). See
Nosyıs ROM uncompiling for moreinformation.*ENDLOADRPL@This
experiment brings evidence that the BUSCC new hp49g+ saturn
ROMemulation command needs to be called from a precise
location tooperate.since it is used in other instructions
that do not make any beep orclick, nor that BUSCC may yield
the slightiest beep alone and calledfrom a user-deŜned saturn
ASM program anyway ;-))Since that command is quite often found
in the new ROM, it is likelythat the BUSCC command behaviour
DEPENDS on the value of the ŜrstReturn STacK level.As a
conclusion, it is highly doubious that such a command could
beused directly inside a user program (as said before). Calls
toroutines including the BUSCC command would be mandatory,
just like toperform a OUT=C C=IN we already used to call
OUTCINRTN in #01EECh(HP48GX) or in #0020F (HP49G).An
interpretation of these results would be that the ARM9
emulationcore can be called for precise purpose with the
BUSCC command only byROM-based routines.(the following lines
are to try to answer to the frequent request ofaccessing to
ARM9 direct programming)Perhaps is there, deeply hidden in
the levels of Flash System Rom, aroutine that uses BUSCC to
read as ARM9 code the content of (D0) or(D1), but this is
*NOT* for sure.Else, I also strongly doubt it is even
possible to write a native ARMcode based program on the
hp49g+.Note by the way that it is now obvious that without
the call to theroutine #3FEF1 using BUSCC, the main makebeep
routine is worthless.Perhaps that so is any LC 8xx OUT=C
sequence...Anyway, I wasnıt able to get the slighliest beep
or tick using theOUT=C command directly.Yoann.====We could
have guessed that although the hardware has very muchchanged,
the Input/Output RAM of the 49g+ could be the same as the
oneon 49G.It appears that a certain number of things have
been deeply modiŜed :1. Adjusting the contrast is made
writing discrete values that eitherincrement or decrement the
contrast, and no longer poke it at thespeciŜed value.2.
Controling the InfraRed is not the same, both in RedEye and
RS232mode, and trying to use it as previously yields to no IR
emission norreception (that was a test with remote
controls).3. The clocks have changed too : only the #137h
nibble decreases each1/16th second, but the #138h 8-nibble
clock is constant and doesnıtchange (or did I miss something)
either in show clock mode or not.4. The vertical refreshing of
the diplay SEEMS not to be able to betested with #129, that
has been proven constant with a recording ofthe #50 Ŝrst
nibbles of #100during one second at the frequency of 128 Hz.
If it changes, it mustbe often the same value and change at a
frequency superior to 128 Hz.Does anyone know the hp49g+
screen refreshing frequency, by the way ?Yoann.====>

http://page.mi.fu-berlin.de/~raut/WR49/index.htm#General====I
have just received a new 49g+ that I ordered in for a
customer. Hewas gracious enough to allow the box to be opened
at my store andallowed me to try the keys - I had explained
the potential keyboardissues and ŝicker to him and had showed
him my 49g+ as well. The new49g+ has serial #CN33308xxx and my
own 49g+ is #CN33108xxx. The newone deŜnitely has a much
better keyboard than mine did when new. Inthe meantime, the
press-down-and-wipe trick has more or less Ŝxed allthe keys
that had been giving me problems on mine. The new keyboardis
deŜnitely somewhat stiffer to push though, but I canıt be
sure ifmine was perhaps also stiffer when new and now has
simply gottensofter. Naturally, since I have only tried a
grand total of two 49g+calcs, Iım not sure if this experience
is typical or at allstatistically signiŜcant... just thought
Iıd add my experience forthe record.FYI, I work in a
professional photographic equipment store (inVancouver, BC,
Canada) that also handles computer equipment:-> www D0T
beauphoto D0T com <- (for fear of getting even more spam
atwork...)I recently found out that I can get HP calculators
through a CanadianHP distributer I deal with. If anyone in
Canada, especially on thewest coast, is having a hard time
Ŝnding the HP 49g+ in stores, youare welcome to contact me as
I can special-order them in and sell themfor $195 CDN (right
around $145 US at todays exchange rate). Notethat we normally
donıt sell calculators and wonıt be stocking them,but since
people in Canada seem to be having a hard time locating
the49g+, I thought Iıd mention it here as a possible option
for them. Note that I actually bought mine from Samson
Cables! :-0Hope that little advertisement wasnıt too
inappropriate for thisforum...Anyways, on to the SD card
tests. Today, I quickly compared astandard SanDisk 32Mb SD
card to a high-speed Lexar 256Mb 32x SD card. What a huge
difference! I performed an SD to SD copy in thecalculator
using the Filer with roughly a 100Kb object from an
SDsubdirectory to the SD root directory. The standard SanDisk
card tooka whopping 24 seconds to complete this and the 32x
Lexar took onlyabout 3 seconds! Wow - 8 times faster! Too bad
Lexar doesnıt makeany cards smaller than 256Mb that are 32x
high-speed... I wouldprobably have a hard time using up a
card that big!One thing I just thought of though, is...
whether the two wereformatted with the same cluster-size. Has
anyone tested the effectthat cluster-size has on read/write
speeds in the 49g+? If I hearfrom anyone that thinks
cluster-size is important, I would be happy toreformat both
cards and test again. I borrowed the 32x card fromsomeone and
probably wonıt be able to try again for a while though.Mike
Mander====> One thing I just thought of though, is... whether

speeds in the 49g+? Those two cards have different cluster
size.With FAT16 partitions the cluster size is determined by
how big thepartition is. For up to 15MB the cluster size is
512 bytes but for a 255MB card thecluster size is 4K. How
fast can you read form a card is given by the speed of
thetransistors or memory cells used by the card itself.

FAT16 (which the 49g+ supports)there is not that much sense to
format it using 512byte sectorsYou will certainly loose much
of the capasityBUT if you want more raw speed - give it a
tryFormat it in a PC using some utility program to variaous
cluster sizesstarting from 1/2_KB up to what is possible
(64KB?)The FAT32 would easily support very huge SD with
512-byte sectorsIf not the speed, you save on wasted
bytes:Wolfgangs libraries seldom take more than Orwell
bytesSo maybe a 4K cluster (8 sectors) is the best trade-off
in the future?The 49g+ currently does not have FAT32
support.(some digicameras with CF slots do have the FAT32
support)This would give it a very food compatibility (also
regarding long names)I hope JYA will have time & interest to
add this feature in 2004...====> X> one deŜnitely has a much

that had been giving me problems on mine. The new
keyboardsounds good - what about the sounds of the
keyboard?Well, sound differences were not totally consistent
from what Iremember. In general, the new 49g+ had a sharper
snap sound fromthe keys and the keys were a little stiffer to
push. There were stillsome keys that were louder than others,
but not the same ones as on my49g+. I noticed some keys on
the new 49g+ actually had a very briefand faint high
frequency ring when pressed while sitting on my desk(for lack
of a better term) but I am thinking that with a month ofuse,
like mine has had, they will perhaps become softer and
quieter aswell.One thing I did notice was the following: on
my 49g+, when I pressany key in the upper left part of the
keyboard, I get a very slightcontrast shimmer on the lower
left part of the LCD. It is like thePCB inside ŝexes just
enough, from keystroke pressure in that onearea, that it also
puts slight pressure on the LCD display causingjust enough
distortion to be visible as a shimmer. The new 49g+ doesnot
exhibit this effect at all. Maybe the internal heat-stakes
thathold the PCB in place on mine have not been melted as
well and thereis a slight movement when keys are pressed.> X>

device!Traditionally, for digital camera use, the Lexar cards
have been thefastest. However, there are now some extremely
fast SanDisk cards aswell (at least CompactFlash cards) but
the problem is that SanDiskoften doesnıt advertise changes on
their packaging. For example,earlier this year, SanDisk
upgraded their Extreme CF cards and madethem much faster, but
the packaging didnıt change, so it is anyoneısguess as to how
fast any given card is when you go into a store andtake one
off the shelf. Lexar has been really good at labeling
theirpackages so one knows exactly how fast the cards are.For
anyone who doesnıt know, memory card speed ratings (8x, 24x,
32xetc.) are more or less the same as those for CD-ROM
drives. A 1x cardwould have an average read/write speed of
150Kb/sec, an 8x card wouldbe 1200Kb/sec, 24x -> 3600Kb/sec
and a 32x is 4800Kb/sec. In reality,it is slightly more
complicated than that, but that gives you thegeneral
idea...Depending on the device the card is installed in, one
may not seeequivalent speed improvements though, since with a
faster card, thebottleneck may no longer be the card but the
device. In general, aslow card would be Ŝne for backups and
Ŝle transfers on the 49g+ butŜle from the SD card, a faster
card could help a lot. I was thinkingof transferring some
astronomical databases to my 49g+ (Messier, NGCetc.) and
accessing them from the SD card, so I think Iıll have to buya
fast Lexar for myself as well.One thing I just thought of

it might beo.k. I thought these days surveyors used onboard

in that 80KB net MEMBUT data requires often extra storage,
thus the *only* modern calculator(sufŜcient for the job), the
hp 49g+, has a SD card port for up to 0.5_GBdata.====> 1) 80K
of ram free. Is that not enough to store data and programs?>
80K is certainly OK for most standard surveying programs. You
mightrecall that the old HP42S had a whole raft of such
prorams (which hadto be entered manually, such a tedious
process). There are manyexcellent HP48 surveying programs
available on the web at hpcalc.orgthat would Ŝt comfortably
into the 48GII. Without knowing much aboutthe GII, it appears
to me that the system ROM has been expanded (toinclude a CAS?)
taking a big chunk out of the 128kb that was availableto the
user on the 48G+ .Most of the surveyor programs Iıve seen for
the 48G needed a 1MB card in > port 2 to store the data..> So
obviously, 1MB is deŜnitely not enough!> 1 MB is way in
excess of what is really needed for most surveyingprograms.
Probably lots of security stuff and gimmick programs to Ŝllup
the space.Iıve just had a Ŝrst look at the HP49G+, and to my
mind it is severalfold improvement over the 49G for
surveyorıs use. It would seem thatsome people in HP have been
closely perusing this newsgroup to get afeel of what was
required. To their great credit they have producedsomething
that to my mind is the best calculator produced
forsurveyors;Good points include;Backward compatability with
the 49G and partially the 48 series,USB port for easier and
faster data transfer,SD Expansion port for larger data
storage,Much much better keyboard and layout,Much better

large for pocket use,No IR port,poor location of ENTER keyWho
cares about colours and other crap like that. Any serious

my hp49g+ two days ago.I bring you my impressions.I used the

CN33304407bought in SAMSON CABLESarrived on timeSo :1. It is
more beautiful than in the pictures.2. The screen. I have no
words to tell my happyness. Large. Verylittle reŝection. Very
good resolution. in my opinion - better thanthe hp48 series.of
course better than the blue one...which I dont even want to
talkabout cause it makes me mad..3.Keyboard. DifŜcult issue.
I am using it for 2 days now and havenıtdecided yet if its me
not pressing hard enough or keys sometimes donot register. It
seems to be OK. The keytest goes OK. So I canıtreally point
about speciŜc keys which are doing problems.I like keys to be
soft. I dont like to press hard. in my opinion he TIkeyboard
is better. Why Hp think we have steel Ŝngers ? Of course itis
better than the stiff keyboard of the hp49g but still - Hp
couldmake it softer.The noise - well, compare to hp49g -
everything will be noisier.because the rubber keys are very
silent. But it is a noisy keyboard,but in my opinion - the
hp48g is noisy too. maybe I can say the hp49g+is a little bit
noisier.However, my father is an electrical engineer and I
hope He will openthe unit and we will Ŝnd a solution for the
noise. maybe a solutionto make it softer.meanwhile - It is
not so bad. I can live with that.4. SPEED. WoW !!!! my
libraries are fast as a lightning. I useprograms like vigag
which is a constructural prog. and it draws graphsand It
works very very fast. I dont think anyone needs more than
thatspeed for a calc.5. SD card. Dont know. I dont have money
now for a SD card.6. PC connecting. Well, I tried to connect
with my girlfriend computer( WIN98 ) and no matter what I dd
- it wouldnt connect. the pcrecognize the calc. but no
connection.With WIN XP pro - no problems at all. smooth and
clear. perfect. fasttransfer, very simple to use. just
perfect.I really donıt care about it but I am afraid that
Microsoft areinvovled in this issue. They think Win 98 isnıt
IN anymore....7.New functions - didnıt Ŝnd any yet (compare
to hp49g rom 1.16)8. competability with older libraries -
stil OK . all my olderprograms works well and you can read
the thread about the libraries. good than the hp48 case - but
i think it is better.All I can say is that I expected better
keyboard. But - and thatsimportant - I dont think I am going

will make an F-16 aircraft plane noise...If you have question

(esp.http://www.hpmuseum.org/guest/brogger/hp49gpk8.jpg ) I
wonder if thekeys which make the most noise are those which
are far away from amounting point on the PCB. If the PCB is
acting as a sound board(like in a piano) and amplifying the
clicks, then the points where thePCB is least supported
should vibrate the most, and be loudest. Iknow my . key is
the loudest of all, and it is furthest from a PCBmounting
post.If that is the cause, then some non-conductive
insulation squeezed inbetween the PCB and the back case
should help a lot.I do notice that the arrow keys are
different than all the rest, astheyıre mounted on a ŝexible
plastic sheet, while the rest arehinged. Maybe the plastic
sheet reduces the local click noisesescaping around the keys?
(But I also note that the keys in the toprow are at least as
quiet on my calculator as are any others.Keep experimenting

difference is that the former puts the calculator intokermit

theconnectivity kit wants to see.Once you do that, youıll be
in business.HTH====> I assume you put the calculator in

electronics. A couple years ago, when I decided that my life
wasnıt stressful enough, I decided that Iıd return to school
for more education in engineering. Since Iıd used HP RPN
calculators then, I wanted to purchase a new one.Despite the
tepid reviews of the 49G, I went and purchased one anyway.
But the bad screen and the rubber keys requiring cleaning
from my dirty Ŝngers at work, and the incessant pauses and
crawling speed during calculations and graphing were more
than annoying. I also longed for the big ENTER key from days
gone-by. Despite the ŝaws, I still would have used the 49G
over any offering from TI and it never let me down. When the
49G+ became available, I decided Iıd upgrade despite having
the 49G just a couple years and reading the sometimes
horrible reviews about the 49G+. Yes, you could say I had
been warned.HP49G+ First
Impressions~~~~~~~~~~~~~~~~~~~~~~~~This reminds me of my Ŝrst
HP calculator vintage 1985 with the gold face and black keys.
The keypresses do have a hollow thump to them, and unlike
HPıs prior work, the key holes are missing that classy bezel
around them. Not what I was expecting, but then again we live
in a consumer mass market for electronics and this isnıt any
different than some of the cell phones and other devices Iıve
seen. Yes, I too still expect that added effort from HP, and
canıt understand why a calculator that is far from mass
market needs to be produced as such.A couple of the keys have
a bad mask on them and while itıs not enough to warrant a
return, itıs obvious that in this day and age, the quality
control ofŜce reports right to the corporate controller. If
anyone from HP reads these things, you could have easily
jacked the price-up $50, added the button bezels and a
retro-keyboard and I would have lapped it up like a biscuit
in gravy. Afterall, Iım of the opinion that the
user-interface objects for electronics (like monitors,
keyboards and mice) are NOT the place to cut corners.After
carefully cutting the packaging for the HP49G+ and removing
it and the accessories, I have to say the Ŝrst impression was
good until I inserted the batteries per the instructions and
stabbed the power ON button. Nothing. Ok, Iıll try again.
Nothing. Sheepishly, I had to hunt for a paper clip and give
my new toy the Ŝrst of several kicks in the fanny. I inserted
the paper clip, carefully found the recessed reset and gave it
a push. I ŝipped the calculator over, hit the on button and
watched in horror as NOTHING happened. No joy. Ok, this is
bad. I pulled the batteries out, waited 10 minutes, inserted
them again, did a pre-emptive reset and lo-and-behold, it
sprang to life.I was at home setting the contrast and doing
some preliminary set-ups. After all, this is pretty much a
49G. I entered some functions and felt the quick
transformation of disappointment to moderate approval as this
thing whipped through solutions and graphing with noticeable
speed. The buttons, while noisy, still felt better than the
rubber keypad of the 49G and did not miss a single input. And
while Iım on that subject, letıs be candid here; a button
press on the HP49G+ sounds hollow because the darned thing IS
hollow. Thereıs a lot of empty space in there and while Iım
not in the habit of being anyoneıs apologist, itıs more than
tolerable. Iım certain thereıs some QC problems with 49G+
units having chronic keypress issues, but fortunately mine is
not one of them. And weıre going to soon Ŝnd out how good the
keypad is because the well water in my home is high in
hydrogen sulŜde (15 ppm untreated). Even though I chemically
treat it and itıs undetectable to the nose, thereıs still
some in there and it tests the engineering of all electronic
devices.HP49G+ The Bad, the Ugly, the
WTF!~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~After the initial
false-start and disappointments, the calculator did still
please and amaze. Oh, and yes, frustrate.Oddly, the button
layout is not identical to the 49G. CAT has been moved to
right-shift SYMB. EQW, formerly its own primary button, is in
the same place but is now right-shift Œ, and EVAL is now a
primary button that was formerly right-shift SYMB. Why they
did this, I donıt know and in my case, is a touch annoying
because of the way I used my 49G. Is it a major issue? No,
just a little strange.The biggest disappointment sits
squarely with the documentation. The books for the 49G were
simply horrible and what you get with the 49G+ isnıt anything
to write home about either. To HPıs credit, I havenıt found
anything that is incorrect and subsequently leads the user
down the primrose path. But like its predecessor, the basic
user guide gives a rudimentary foundation. Gone from HP49G
days is the advanced (albiet not entirely useful) guide and
the actually somewhat useful pocket Even more thankfully
there is Google for searches on how to do things that are
missing from the manual.Also available is a 10 megabyte PDF
of more documentation that is not entirely useless. Itıs also
on HPıs web site. In my opinion, it seems to be on the right
course to being a decent guide for doing advanced math on the
49G+. Again, if anyone from HP pays attention to these things,
please consider what I said above and consider the fact Iıd
easily pay an extra $60 for a retro-keyboard, add some
anti-thumping mass to the product (for my friends here on the
newsgroup) and throw in a set of printed documentation.
Remember, a key market for this thing is students and a PDF
doesnıt travel all that well unless itıs printed out. And who
wants to print out nearly 900 pages?The HP49G had a sliding
cover, which many people disliked. Iım usually a
non-conformist and ergo, I actually thought the sliding top
was pretty cool and liked it. Now you get a very nice leather
case with a magnetic clasp. The true value of the magnetic
clasp becomes apparent after your second calculator lockup.
Itıs a convenient spot to hold the ERD (emergency rescue
device) without damaging the leather exterior of the case.
The ERD is a paper clip. Yes, my magnetic clasp secures a
paper clip quite nicely. Granted, upgrading the Ŝrmware has
stopped all the crashes, but as far as the ERD is concerned,
Iım not about to leave home without it just yet. And while
the leather case is classy, it adds considerably to the
dimmensions of the stowed calculator and I canıt Ŝt it
securely in my book bag. Of course, being a non-traditional
student, I simply canıt use a backpack lest I be accused of
having a mid-life crisis or other identity ŝaw. Nope, I need
a $200 satchel soft-attache that is functional, attractive
and doesnıt scream I wish I were in my 20ıs again like
everyone else in here. Truthfully, I do, but I digress and
that doesnıt change the fact that I need to Ŝnd something
else in which to carry my books and HP49G+.The biggest pain,
frustration and WTF moment has been using the connectivity
kit. I installed from CD the software onto my Sony Vaio
laptop running Windows 2000. There is little installed on the
laptop aside from an SSH client and Opera. It is normally
exceedingly stable. Yet, the USB driver for the 49G+ caused
the poor machine to blue screen at least half a dozen times
while trying to talk to the calculator. Unplugging the USB
keyboard and mouse solved nothing. When it wasnıt blue
screening the laptop, it wasnıt communicating with the HP49G+
either. There were two problems.First, the USB driver shipped
on the CD is apparently ŝawed. Second, the instructions given
in the connectivity kit from the CD are not exactly clear on
how to communicate with the 49G+. The solution is to ignore
the CD and download the latest drivers and connectivity
software directly from the HP web site. Once installed, I was
able to communicate with the calculator and load the much
needed Ŝrmware upgrade. As I posted here previoiusly, the
proper keystroke to start communications on the 49G+ is
right-shift (release it, donıt hold it down) and then right
arrow. Thatıll kick it into Xmodem transfer mode.Another
source of weirdness has been the calculatorıs refusal to play
nice with my older Sandisk SD cards. Absolutely no problem
with my newer and larger SD cards used in my camera, but the
older 64 megabyte cards that I have and would like to
dedicate to the calculator seem to be exceedingly slow or
simply will not work. They work in other devices just Ŝne and
even though Iıve formatted them in the calculator, they are
simply not working. All other cards I have work just spiffy.
Realistically, this may or may not be a problem with the
calculator.HP49G+ The Reality of the
Situation~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~I donıt believe
the detractors of the HP49G+ and their claims can be easily
dismissed. Itıs obvious that quality control problems exist
along with some proŜt-centric design decisions that, as a
former company, were out of character for HP.Nevertheless, an
upgrade from my HP49G, this calculator is a welcome increase
in speed as well as a vastly improved display. The display is
larger, has a better aspect ratio, better viewing angles and
doesnıt suffer from glare as badly as the 49G. I like it. And
compared to the 49G, itıs blisteringly fast. Yes, itıs
probably just as fast as a TI now, but then the TI doesnıt do
RPN and that seems to be one of the major reasons for buying
these darned things.Somewhat assuringly, HP hasnıt completely
turned its back on the ŝaws. soon and thereıs improved
connectivity software on the web site. Despite the
false-starts, frustration and some lacking supporting
materials, I like my 49G+ and itıs already serving me
well.Plus, it seems to give the correct answers to the math
problems presented, which is always helpful.Your mileage may
vary.====Why does HP do this?They must know from endless
comments that we want the old HP41 keyboardback. How much
extra would it cost? The complaints and tepid

thatıs what hp is counting on. them not ever having seen

Ŝlling in the hollow space isgoing to fool anyone--although
replacing the Œtin drumı faceplate wouldtruly help.true
quality rarely depends on just a few discrete components or
can beimbued with just a few parts changes--it must be

others nowadays, seems to have solely beendesigned to a price
point and it saddens me. what would have been wrongwith
designing the best quality calculator Ŝrst, then using
thatdesign to sell an economy model to poor students and
such?iıll bet others would agree that we would have been
willing to pay atleast twice or three times the price to have
the pride in a qualityinstrument. that factor used to be a
huge selling point for hpequipment, and, even if hp quality
didnıt quite force ti to match it(or, most likely ti couldnıt
match it), it did force ti to keep tacitlyapologizing for how
badly they suffered in comparison. now, some of us who would
have never previously even contemplatedowning a ti have at
least tried one because hp quality has slipped sobadly.
thatıs why weıre now reduced to comparing chip speed

wouldnıt be a problem.Well, letıs see. If you have receive
pacing enabled but transmit pacingdisabled, then an XOFF or
XON in the data stream coming in to thecalculator isnıt a
problem. But if you have transmit pacing enabled,then an XOFF
or XON coming in to the calculator is treated as a ŝowcontrol
signal, not data, and never shows up in the input
buffer.Similar considerations would apply to the other
device, although I donıtknow of any other devices where
transmit and receive pacing can beenabled/disabled
separately.Well, I donıt expect that my printers even have
the option to dotransmit pacing, but the only thing that they
ever transmit are the XOFFand XON signals.And of course it
does no good to have receive pacing enabled on onedevice
without having transmit pacing enabled on the other device,
andvice versa.> If I was using a PIC or other microcontroller

a CLOSEIO. The only thing that I know of (otherthan CLOSEIO)
that closes the I/O port is turning the calculator off,either
explicitly or by an auto-off. But whatıs the point of doing
aCLOSEIO anyway?I guess that youıre transmitting from the
other device in 255-bytechunks with a sufŜcient delay between
them that youıre certain that thecalculator will have time to
process what itıs received and be ready andwaiting for the
next chunk? Well, it might work. Also consider a stopand wait
method where the calculator sends back a signal that itısready
for more data.-- James====> If you want your project to work

on software ŝow control. Rather a shame, isnıt it?But on
second thought, it might be possible to implement, more or
less,your own XON/XOFF receive pacing on the calculator. Say
start out bytransmitting an XOFF, then doing a BUFLEN
followed by an SRECV, thentransmitting an XON, followed a
short time later by an XOFF. Whetherthis would work would
seem to me to be a matter of timing, and woulddepend on the
transmission speed, how fast the other device responds tothe
signals, and how fast the XOFF could be sent after the
XON.And for transmit pacing, check all strings received and
anything stillin the input buffer for an XOFF signal before
transmitting. If an XOFFis in there, then remove it from the
data stream and set a ŝag of somesort for donıt transmit.
Then check the remainder of the data for anXON to be removed
and clear the ŝag if itıs found. When the inputbuffer is
empty, everythingıs been checked for XOFF or XON signals,
andthe ŝag is clear, send a small (small being deŜned by
thecharacteristics of the other device) chunk and then check
the inputbuffer for XOFF and XON signals again before sending
the next chunk.And of course if the other device uses some
other pair of ŝow controlsignals, youıd have the calculator
use them instead of XON and XOFF.I donıt know; it sounds
pretty clumsy, but itıs something to thinkabout, and perhaps
experiment with.-- James====> Actually, I want to disable the

Fact: There is now evidence of terrorist ties from Iraqi
documents. This is why we went to war anyway. Fact: About
3000 people died in the US when we were bombed with the
airliners! Many of us ignorant Americans remember this. Fact:
We Americans reserve the right to wage war on those that act
to destroy us. > Fact: In the Œrebuildı of irak only american

This is how it has always been. Read your history. Why would
you give contracts to those that do not support your efforts?
Do you favor those that hinder your efforts? Anyway. This
seems to be a very economic-war... Fact: All wars are
economic, another history lesson. Fact: We occupied Japan and
Germany also. It seems that the best way to gain ecomomic

will Ŝnd that most Americans do not trust American media. Do
you trust yours? We Americans have many faults and make many
mistakes but we take action when everyone else just wants to
talk. now let us get back to calculators Merry Christmas and
Happy New Year!> Greetings.====well your speech seems to be a
very imperialistic one... perhaps if you lived about 100 years
ago your kind of speech would be acceptable, but not in todays
world. It is because of this type of reasoning that the there
is an increasing hate for americans in the world.you seem to
care about nothing except yourselves, and nobody likes selŜsh
people.and about the 3000 americans that died. iım sorry,
nobody deserves to die! But americans, in their so called
colateral damages, have killed many thousands more. even in
the past month 12 afegan children were killed...by the way,
throughout history there have been many empires, but they all
fell... <bsnhue$b85$1@nyytiset.pp.htv.Ŝ>

For Food Programme?
<http://www.un.org/Depts/oip/background/index.html>If you
read carefully youıll see that, of the funds from oil sales,
2.2% went for United Nations administrative and operational
costs and 0.8% for the weapons inspection programme. All the
rest went on food and medicine for Iraqis.By way of
comparison, the American Red Cross had Management and General
operating expenses of 5% with a further 4% spent on fund
raising.
<http://www.redcross.org/pubs/car03/annual_rept_insert.pdfDo
not forget the mass slaughter uncovered in Iraq.Indeed. But
surely Bush senior put a stop to that with the introduction
of, for example, the Kurdish autonomous region in the North.
Or are you saying that, for the 10 years or so of the
enforcement of the no ŝy zones, America knew of mass
slaughter but stood by and allowed it to happen?> Fact: To
the victors go the spoils, This is how it has always been.>
Read your history.I wouldnıt say this statement was
universally true. If we consider just the major wars that the
Americans have been involved in then it is only 50:50.- in the
Indian wars you slaughtered the natives and stole their lands
- a classic case of the victor getting the spoils- after the
Ŝrst world war, huge reparations were demanded (admittedly by
the French mostly) but Germany was never able to pay them, so
50:50- after the second world war the Marshall Plan meant
that the losers gained signiŜcantly - the exact opposite of
your argument.> Why would you give contracts to those that do
not support your efforts?Contracts should be given to those
who can most efŜciently carry out the work. These will
inevitably be local Ŝrms and other than for specialist work,
no western Ŝrms, American or European, should be getting much
work.> Do you favor those that hinder your efforts?You are
confusing the actions of European *governments* with European
*companies*.>> Anyway. This seems to be a very economic-war...
Fact: All wars are economic, another history lesson.Does this
include the second Gulf War? Earlier in your post you said
that the reason for the war was to destroy WMDs.> Fact: We
