Well, hopeully this will be the last word on the subject.. Or at least will
end the 'I have the problem', 'I don't', posts.

This is what is happening.  With the zipper case, when you slide the calculator
into the case the keys all rub against the top edge of the inside pocket.  This
tends to deposit oil and dirt on the padding there depending on how clean your
calc is.  When the calc lives in the case for a while in your backpack or
whatever that edge of the passing WILL rub against the display, but it leaves
or doesn't leave a mark depending on whether it is dirty.  If you routinely and
concienciously clean your display then it doesn't seem to build into a problem.
If you don't clean your display or case now and again, then it WILL start to
build up and eventually, the little bit of well worn dirt on the display will
start to scratch and the mark becomes permanent.

When I went to clean my display the first time I noticed the mark I found that
a regular cotton cloth wouldn't take it off.  However, when I used the special
cloth I have for cleaning my sun glasses I found that it would take the mark
off.  Unfortunately, I have now met some people who are not so lucky and the 
mark is now permanent.  It probably won't get any worse now that they know 
what is causing it, but it isn't going to get any better either.  I see two
solutions:

1, Keep your display, case, and keys clean at all times.  This isn't always
easy for the person who uses their calc in the field.
2. Get another case.  There are probably some velcro cases floating around
somewhere.  There is a leather case for the hp48s*, and a case for the hp41
that works with the hp48.  There are also numerious interesting camera cases
that will work quite well.

If you have any other clever solutions, let us know but for all your people who
responded to my question, thank you.  I believe all the people who said they DO
have the mark, and all those who DON'T have it.  It's just a matter of your 
particular circumstances. 

That's the news.. and I am... outta here.

My display isn't worn, but since it seems that EVERYONE on this channel wants to

Subject: Wish list, touch screen and pen based HP48sx!!!!!
Date: 15 Apr 92 02:33:48 GMT
Organization: Brandon University, Brandon, Manitoba, Canada

I would like the next generation of the HP48sx to have a touch screen.
My idea is that the whole calculator is simply a touch screen with a few
function keys and smooth cursor keys (just like the flat-joystick on a
NenTinDo family game). There is no key label because the screen that correspond
to a key will print out the function of the key. Thus, the new HP48sx only has
the cursor key, on/off key, alpha key, left/right shift key, all other keys are
in the form of touch screen. This will save a lot of space and enlarge the
screen a lot. Something like the newest pen-based laptop computer. If possible,
a touch pen on the HP48sx screen is better than a 'MoUsE' ball under the HP48sx.
Besides, the new HP48sx should be able to view horizontally or vertically. I
mean you can hold the HP48sx vertically just like a calculator and hold it
horizontally on both hands like a palmtop. No more template, the touch will
change the key layout according to the programs. You may program a touch screen
with [SIN] [COS] key together with another touch screen with standard typewriter
style keyboard or an APL keyboard. 

Think about it!

it may sound unbelievable - but it _works_! A friend of mine had an
awful crash on his 48sx, and both pressing RESET and taking out
the batteries for a little while did not bring it back into life...
but since he had not enough time to wait... he reversed the batteries and -
voila - the calculator's mind was erased and it began to breath again...

Joe,

I have gone back and couldn't eval backup objects as you indicated
it can be done.  I just couldn't apply your FOO BAR example to
my situation, so here's an example:

Directory Structure:            {HOME}----{GAME}----{PACMAN.DIR}
                                                 | 
                                                 --{VADERS}
                                                |
                                               --{TETRISX}        

OK, Say I back it up to bank one of port one with:
:1:BGAME STO
after putting the "GAME" directory and contents on the stack.

I am able to recall it from bank one port one with: 
:1:BGAME RCL
just fine.

Given this example, how do you play, say, pacman out of the RAM
card?
Be advised tetrisx and pacman both have variables that must be written
to and read.  Does the "Just like a ROM card" statement still hold
true?  Thanks for your trouble,

Watch out out there!

There IS a virus on the HP48!!!!
It looks quite unattractive and not realy reproducable here (don't have it).
THere is a 'curing' program. You know where to get it if you want to ;-).
B.t.w. the game ANT displayes a 'funny' message when you have crushed
level 4 (anyone beside me done it?). One of the messages is:
"Virus installed"

We asked the author about it, and he swore he never ever had written a
virus on the HP48 and he regretted the mess. Don't flame the guy for it.
Anyway, there IS a virus, but it ISN'T ANT.

   I recently noticed that the UTPT (upper-tail area under Student's t
distribution) command will not allow the degrees-of-freedom argument
to be greater than 499.  Now I know that as the number of degrees of
freedom gets large, Student's t approaches the standard normal
distribution.  However, even for DOF=499 the values returned by:

		0 1 X UTPN

		   and

		499 X UTPT

for X >= 0.2 agree to no better than 3 significant digits (rounded).

   Can any of the HP48's designers reveal the algorithm used by UTPT?
Why doesn't it allow DOF > 499?

Is this what passes for ethics?

I know people tend to rationalize even blatantly immoral behavior, but this is
some of the weakest rationalization I've ever seen.  Why on earth does buying
an expensive gizmo entitle you to a grade you couldn't earn otherwise?

Too many people believe that life is all about money.  So many believe it, in
fact, that it's started to come true.  Do you also believe that education is
about money?  Is it a matter of learning something, or buying your way through?

Somebody ought to show all your professors where your calculator's hardware
reset button is.  You deserve it.

On second thought, you deserve a lot worse.

I had the same problem, but I solved it in a rather bulky way:

1: Run TASC and deASC the files on your computer.
2: Run TASC and ASC them back to ASC format
3: Transmit!

Of course it's not the best way to do it...

I got one on sale for $240 last month at our local Service Merchandise
store (I'm assuming that all Service Merchandise stores had them on
sale)  Plus if you have a Service Merchandise card you get no-intrest,
no-payment for 90 days.  No shipping but you do have to pay tax.
Seemed like a Hell of a good deal to me.  The salesman said the
regular price was about $20 more which is still a good deal.

I have no affiliation with Service Merchandise other than being a
satisfied customer.  Opinions are mine alone and do not represent

Wow this is really strange. I have had my HP48 for about 21 months now
and have NO signs of wear. I think that I've seen what your talking
about on other HPs but mine doesn't exhibit such signs. I use it often
and it is a made in USA model. Also has anyone else noticed that for a
while the HP48 screens ewere lighter and NOT as green as the ones being

most of the ones I see which are a strong green. Oh yeah I have a
