When I did some calculatione, the zero-key on my HP49g+ died!
ARGH! I need it!
Did this happens often? Is it possible to repair myself?

Are all the newer HP calculator a load of crap or has a HP50 a better
keyboard?

Oh..and is there a how-to-open manual for the 49er?

That's a well-known fault in most of the HP 49g+ calculators. This is fixed
in the HP 50g. They changed the type of plastic used so it doesn't break as
easily.

I'd be happier with the 50g if they'd put the enter key back where it
should be.

Why? Having used HP48GX previously on which the ENTER key takes up
the space of 2 normal keys without any additional functionallity the
Enter key on the HP50g has ":ANS": and ""NUM" to accommodate a more
superior product than the fabulous HP48GX

Virtually all of the numeric key on my 49g+ are broken (keys 7 and 8
still work normally). With some effort, the broken keys still work
but you have to watch the display carefully to make sure the number
was actually entered. I have a 50g and recently bought a 2nd used
one. The keyboard on the 50g is much improved.

I don't know of a how to open manual. Best of luck.

That large [ENTER] key on the classic HP calculators was one of the
hallmarks that proclaimed their heritage as serious scientific instruments
designed for expert users, not just "appliances" for the average person.
Getting rid of the large [ENTER] key was part of the dumbing-down process
when HP started deemphasizing RPN and RPL in favor of algebraic notation.
It's one of the reasons why I have no interest in owning or using any
HP calculator newer than the 48GX.

I suppose that you would have a Remington Typerwriter after IBM came
out with the golf ball typewriter. There are those who bemoan the
fact that Hewlett Packard decided that the HP48GX was more of a gadget
for nerds,than to appeal to what the calculator market demanded. Just
as Nokia are now finding after Steve Jobs brought out the iPhone. The
capacity of the HP48 series was limited by the need to purchase
preprogramed cards and the shocking connectivity kit that came with
it.One major advance was the ability was to be able to enter algebraic
expressions as they are written and also in RPL form which was
retained in the HP50g.The best thing that HP did was to get rid of the
slot cards and incorporate the use of SD cards to allow off-calculator
programming and saving those programs on the SD card.What could be
more attractive to a calculator user.The Curta calculator was a marvel
in its day but then who would use one now as a common low function 4
basher can do one calculations in a blink of an eye. Also why even buy
a calculator when there are emulators galore on the web.

For the record, I prefer Smith-Corona typewriters over Remington. Also,
I use a Nokia phone and don't care at all for the iPhone. My favorite
calculators besides my HP-48GX are my HP-16C and HP-41CX. I still
use some of my slide rules (K+E 4081-3 and 4081-1, Post Versalog, and
Pickett N600-ES) from time to time, too. The HP-16C, the K+E 4081-1 and
the Picket N600-ES are especially convenient since they're pocket-sized.
