Subject: Re: How does one store a directory as a soft menue key?
Only libraries install by storing into ports
A directory is a user variable; just leave it
wherever it was when you copied it to your calc
(its menu label will have a tab showing that
it is a directory; press that label to enter
the directory).
Is it an MES-based triangle solver?
That ought to be fun, given how hard it is
to make MES work with that kind of problem.

How do you delete all of the Y1-Y88 using the filer? Please tell me
===
Subject: Re: Graphing functions.
I just opened Adobe Reader 7.0 and searched all three
main HP50G publications (Manual, Guide, and AUR)
for all occurrences of the string filer
(any case, any part of word).
The Manual and Guide searches found one mention each,
in connection with using an SD card; the AUR mentions
that there is a FILER command, to start the filer.
Would someone like to fill in the rest?
(or perhaps revise the indexes in those documents?)
.
===
Subject: Re: Graphing functions.
Since filer wasn't a very successful search word for the PDF manuals,
and since somewhere the Filer was also called File Manager,
I tried searching for manager -- had a bit better luck:
User's Guide, Chapter 2, has a section
Organizing data in the calculator (starts near page 2-33),
which describes the Filer!
I hadn't the patience to read through it all,
to see whether it mentions that in the Filer,
the ENTER key selects an item and them moves
to the next item; if you hold it down, then it
keeps selecting consecutive items (up to 99),
to which the next subsequent action (e.g. PURGE)
will be applied.
It would be useful to first alphabetize the displayed entries,
so that all the 'Ynn' might be more or less consecutive in the listing.
To alphabetize, find the SORT label in the filer menu, or:
The N key also alphabetizes in 49G, but in the 49G+/50
the N key instead does EVAL, so try shifted N instead
(for reverse and forward sort).
This post will self-destruct in six days,
so memorize it for future use,
because you'll never find it again :)

Subject: Re: Graphing functions. [File manager functions]
[re: searching for the elusive Filer or File Manager instructions]
I remembered that my 49G+ came with one printed book,
which turns out to be the Manual
(not the Guide, and not the AUR)
I flipped through, and looked for a picture of a Filer screen,
but didn't find one. Well, that can't be a very important feature,
since it can only be found by tedious scrolling through
a computer screen, after inserting a CD into the laptop
which one always has at hand in case a calculator question comes up :)
There was once at least a pocket guide for the original 49G;
I wonder whatever happened to formerly good ideas like that?
I recall that some companies' publications show an image of
their product's keyboard, and then proceed to give a brief tour
of what each function (or group of keys) does for you;
that's not the only way to do things, of course,
but it would make a nice orientation sort of thing.
To get the basic instructions for navigating (and selecting)
in the Filer, it seems you may need to locate earlier documentation,
by the software authors themselves (after reading which you'll surely
appreciate more of what they've put into the product):
http://www.hpcalc.org/hp48/apps/mk/mk230pdf.zip
You can also hunt through ancient newsgroup postings, e.g.:
It is always good to keep a few things secret, however,
reserved for members only -- who knows the vulcan grip
for entering the secret Netware debug console, for example?
Is that how Netware literati recognize each other at meetings?

applies to the entire series, which is essentially
just one basic model, with only slight feature variations:
48 - no flash, 8-line screen, serial, no USB.
49 - flash, 10-line screen, USB, no serial
50 - USB+serial, USB-powered, 4th AAA cell.

Subject: HP 82240B After-Market AC Adapter? RadioShack
The below is from research that I did on-line about HP AC Adapters (no
longer made) that are original equipment. I did find some adapters on-
line at RadioShack.com that seem to fall within the voltage and
current parameters. See HP made two AC adapters for these printers
below.
Does anyone have any experience with this and perhaps a model number
and vendor?
The prices on eBay are for the most part very high. I am in the USA.
Frank
HP made two AC adapters for these printers.
[ADAPTER 1] The earlier HP 82241A adapter is rated at 9V AC 13.5VA
MAX; The 82241A uses a fixed input voltage and frequency (120 V 60 Hz
for the U.S. option);
[ADAPTER 2] The later HP F1011A at 12V DC 0.75A. the F1011A takes an
input from 100-240V at 50-60 Hz and is much lighter, but runs warmer.
I believe that both are available in various options to fit various
styles of outlets.
http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv013.cgi?read=43655
[] What is the required voltage and current for the AC adapter?
The adapter should output either AC or DC at 9 volts. If the output is
AC, then the minimum current is 350 milliamps. If the output is DC,
then the minimum current is 175 milliamps. The DC output plug can be
either polarity.
The AC adapter made by HP is the same one used for the HP 82240A
Infrared Printer. Different versions of this adapter are made to
accommodate the AC power in various countries: HP 82241A for USA and
Canada (110v 50-60Hz), HP 82241AB for Europe (220v 50Hz), HP 82241AU
for UK (240v 50Hz), HP 82241AJ for Japan (100v 50Hz), and HP 82241AG
for Australia (240v 50Hz).

Subject: HP 50G External Power
With the relatively short life of the HP 50G batteries, and the
capability of powering it through the USB port, has anyone made up a
external battery pack using D cell batteries or a well filtered DC 6v
power supply for use in a home environment where portability is not
vital?
It seems to me that this would be a logical step rather than powering
up a PC and attaching the calculator to it. Should be relatively easy
to do too I would think. Possibly a product for someone to make!
Along those lines too the USB cable that comes with Canon digital
cameras has the same equipment end connector as the 50G USB cable and
works fine with it.

How do I know which ones are compatible with my Hp 50g? Should I save
my memory before downloading these files? Will any of them mess up or
erase contents in my calculuator? What is the fastest way to save ALL
of my memory (except HOME because I think that stays there forever)?
===
Subject: Re: Any good programs for Algebra, Geometry, Trig, and Precal?
Try any programs at www.hpcalc.org indicating the HP49 symbol,
since all HP49/50 series are essentially compatible,
because one ROM fits all
Binary files for any other calc series have a file prefix
which the 49/50 series won't accept anyway;
thus it's not possible to accidentally use binary files
in the wrong calc series.
User-stored programs and data (VARiables) in HOME,
are in fact the very thing which needs backing up,
(in which languages many contributed programs are written,
by programmers of varying skill and sense).
How to back up to on-board flash:
PUSH :2:BK001 ARCHIVE
(increment file name for each subsequent backup)
How to restore from on-board flash (if needed):
:2:BK001 RESTORE
This concludes with an automatic warmstart,
after which a POP command will restore flags, too,
if you had originally done PUSH as above.
If you have an SD card, you can use port 3
in place of port 2, to write/read the SD card.
It is, after all, much like sampling programs for your PC
from sources all over the internet, by all sorts of authors --
some may work, some may crash, some may corrupt your data
(even though most won't), so you may prudently
back up your critical files, just in case.
For another means of trying out software in complete safety
(and convenience), you could try first in an emulator,
on your computer, immediately upon download from internet.
Isn't it good that these calcs are not yet internet-capable,
so that they are not targets for adware/spyware/viruses/rootkits/etc. ?
Wouldn't it be nice if ON+A+F would reset your computer
and clear it of all problems, no matter what had previously happened?

Invalid Syntax. I don't know what is wrong here. Also, I've read in

not being able to be backed up, only copied. Are we just copying
into the Flash ROM so that you can extract it later?
Does the HOME directory contain everything (eq. library, CAT, units,
applications)? I viewed the HOME and it only contains units and Casidr
and some other things. Is this the only file that I should back up?

Some manufacturers of everyday universal AC (multi-voltage)

Now that there are standard small connectors which fit into calculators,
HP has taken to using the common industry-standard connectors and cables,

that research was done to avoid harm in case a USB cable
is actually plugged into it).
No more sharing plug-in card pins and extra serial connector pins

Subject: HP50G user review
I recently ordered and received HP's new
HP50g having previously used HP49G+, the
HP41CV, and the HP12C. Comparison will be
made mostly to the recent HP49G+. I'm hoping
my own review of the HP50G will help someone
else, just as some things I've read about
the HP50G on this group have helped me.
I have to say that, just as I'd hoped and
just as others on the list have indicated,
the HP50G is impressive and definitely a
worthwhile upgrade to the HP49G+.
Out of the box, the 50G is a bit heftier
than the 49G+. It's solid, has a good grip,
and has returned to traditional HP look and
feel. The colors chosen for the keyboard
are superior to the 49G+ and the contrast is
such that it is easier to see your way around
the keyboard for the key you need. To me it
seems the color scheme makes the the whole
keyboard arrangement look more tidy and
ordered.
The key tactile feedback is soft with a
light click. Gone is the hollow metallic
'clack' of the 49G+ and gone is the 'Key
Click' that I always had turned ON on the
49G+ just so I could be sure that the key
had registered. This is a MAJOR headache
relief; the constant overhead of always
keeping one eye on the screen just to be
certain the 49G+ had done what it was told!
I trust the keys - they are softer and do
not have the slight rattle that the 49G+ keys
did when you'd lightly wiggle your finger
over the tops of them. The keys on the 50G
are firm but require a lighter touch to
register - another nice improvement to the
keyboard.
I don't care for the directional keys - I
liked the ones on the 49G+ better. The arrow
keys on the 50G are set a little low, feel
just a bit squishy, and you almost don't
have enough travel in the key to get it to
register ( so it feels ). By the time the
arrow key has registered, the key is almost
down even with the plane of the keyboard. I
am glad I don't use them extensively.
The screen is adequate - this is one thing
I liked on the 49G+ better. Very good contrast
on the 49G+ screen - an almost ideal black
on white display and very easy to read. Though
the 50G has basically the same display - it
seems I can never get the contrast to where
I like. By the time I darken the characters
enough, the screen background begins to
darken from too high a contrast. Lighten the
screen back up and the characters take on a
very slight washed out appearance. This is a
very minor issue and only mentioned in
comparison. I've also read about a certain
tint to the display. I have not really
noticed this - I don't think. If I had not
read about it I certainly would not have
noticed such a tint on the unit I have.
The battery compartment door comes off
much more easily than the 49G's - almost too
easy. Not bad right now since this 50G is
new but... if HP offers replacement battery
covers of a different design or material, I
will definitely consider it.
The manual is a mere brief introduction
but we all know that already and we already
own the AUM pdf available online, don't we?
Overall, if anyone is considering upgrading
from the 49G+ to the 50G - my vote is that
you will not be dissapointed and I wish I
hadn't waited as long as I did. The 50G, to
an HP user (IMO), is solid, likable, and most
importantly, easy to use and is an overall
better experience. Important stuff to those
who use their calcs extensively.
Many claim HP is going downhill and still
make that claim. Consider this; the graphical
calculator market can almost be considered
a niche market - HP could survive with or
without us. Despite that - HP heard the
feedback on the 49G+ and came out with the
HP50G which was a major step in the right
direction that was much appreciated. Any
ideas how much it costs to launch a new
calculator model? Pretty good for a tiny
minority in the market niche of the graphical
calculator users, isn't it?

One thing that surprise me is that, after 4 years of VERY HEAVY field

Surprise me it does not scratch neither looses transparency. If I
compare it with the new HP50G the last one looks a little blury .
The HP50G seems to have bit goldener display than the HP49G+, and I
lke more the old one. But both are incredible machines.
