Subject: HP 50g Hardware Reset HELP
a hardware reset as described in HPs training manual.
If the settings are too confusing, it is always possible to do a full
reset of the calculator by pushing an unfolded paper clip into the
RESET hole at the back of the calculator. If the clip is held down for
a short time only then the calculator is reset but the contents of
memory are retained, only the stack is cleared. If the clip is held
down a longer time then the calculator beeps and asks whether the
user wants to try to recover the contents of memory. Answering NO to
this question means that the calculator will be completely
reset and everything will be deleted, bringing the calculator back to
its state as new.
The problem I am dealing with is that I can perform the simple reset
with the clip but not the second one which brings back the calc to its
original state. Any clue whats happening? Always I introduce the clip
for a short or long time it only resets the first way.

Subject: HP 50g EQLIB with Choose Boxes
Does someone know if theres a way to avoid having to check flag 117 on
and off each time I want to use the equation library? This would be
using the libraries with choose boxes.
If not checking flag 117 when I enter the solver in the eqlib it
brings me back automatically to the stack screen after showing the
message starting solver(which never starts) and returns me back to
the stack with all variables with zero value.
Does someone know why they doesn`t work? Is it a bug? Can/will be
fixed in future rom updates?

Subject: Re: HP 50g EQLIB with Choose Boxes
Leave flag -117 set :)
Use the EQNLIB command, instead of starting from the APPS menu.
Yes, a minor problem in transition between the choose
form of menu 113 (the EQN Library Menu which you get
after selecting Equation Library from APPS menu,
but only if you have not set flag -117)
and the subsequent soft solver menu.
It was declared Fixed in ROM version 2.10
(except that this version hasn't yet appeared)
The EQNLIB command doesn't have the problem,
so that's the solution meanwhile
(but only necessary for those who don't leave flag -117 set).

Subject: Re: degrees,minutes and secs.
Yes, someone knows. In fact, I bet there are many who know.
I started this post thinking that I was going to tell you that as far
as I know, the HP48 doesn't have a feature for displaying
degrees/minutes/seconds, and that I'd probably produce a program to
break the one number up into three numbers. That might still be a good
idea, as the feature that the HP48 has (actually, it's for displaying
time) is rather lame. Look at page 12-8 in your HP48G Series User's
Guide.
Now, instead of seeing 22.6576946758, you see 22.3927700833 What's
after the decimal point no longer represents the fractional part in the
proper decimal form; now it's minutes and seconds.
22.39 27 700833 = 22 degrees, 39 minutes, 27.700833 seconds.
See, I told you it was lame.
decimal degrees, before you use it in any other calculations.

Subject: Re: HP 50 keyboard
Part of the problem with older HP49G+ may be physical,
and another part could be due to old ROM version;
in any case it might be good to install latest ROM version,
which will do the best that can be done re key bounce
(and fix old software bugs),
although it can't help with any physical wear-out.
Fixed, with metal dome keyboard.

which continues to have completely fixed keyboards,

Subject: Re: HP 50 keyboard
Hard to believe no one has answered this question yet. Probably because
it's asked (and answered) so frequently. OK. Basically, early 49G+
examples had keyboards which felt OK when new but deteriorated quickly.
HP (or rather Kinpo, the manufacturer making the 49G+) revised the
keyboard design several times, finally arriving at a design that feels
pretty good and seems (so far) to last some time, although no one
expects HP-35 durability levels. By the time they'd made that final
keyboard design the reputation of the 49G+ had been tarnished, and there
were some other issues to address, so they introduced the 50G with the
final, best 49G+ keyboard design, and some other small changes. I've
heard no complaints of quickly deteriorating 50G keyboards, but of
course it hasn't been even a year since the model was introduced.
Anyway, you're relatively safe: it's not crappy.

I am confused here. I was told by a reliable source just a few months
ago that HP has only one engineer working on calculators and the rest
of the work is contracted out. Is that incorrect or by HP calculator
team do you mean that there will be representatives from the
contractors at the event? (Please don't reply just to say that you
can't reply because of some nda bolona.)
