HP48 Backlit?
Bradford Backus
and want to use the calc, or for other reasons need to be in a dark place
while using the calc. Is there any posible way to backlight the
display? (Actually one of those little booklights works nicely, but the holy
grail is backlight.) I don't need color but backlight would be great.
(though batteries...)

why does everyone want to turn a calculator into a gameboy. backlighting,
color, etc.

I don't think the original poster even mentioned having the backlighting to
play games ... careful, otherwise your reply would almost make you look
like a disgruntle TI user ;-) (exposition for the uninitiated - hop over
to the TI ng, and most all post usually revolve around "how can I play games
on my TI" and that genre). - then again, granted, there *might* be hints
that the back lighting could be for gaming purposes ... even so I'd say that
it's really a non-issue. I for one have at times wished for side-lite
screen as my 48 sits atop a hi-rizer and I'm behind the wheels.
Back to the issue ... has anyone who's opened up their 48 found room for
LED's on the side of the screen?

Why? We want to be smart as (put some well respected scientist) and at the
sam time be just kids. Even MS windows comes with some games (gee-wiz look
there's a Minesweeper just like the one on my HP :))

you add features that make it more of a toy and less of a professional
instrument, you diminish it.

Backlighting has nothing to do with being a toy. Are laptops considered a toy
because they have backlit screens?

Heck, my little Sharp 256kb Wizard has a backlit screen... it simply
enhances the readability in reduced lighting (or reduced eyesight)
situations...

3Com Palm IIIx/V. I got one, and it's amazing. The screen is very sharp,
excellent contrast (does grayscale as flicker-scale just like the 48,) and
has a VERY impressive backlight (lights up in "reverse" so that what was
black text on light background becomes lit text on dark background.) I've
found that I only need the backlight when it is very dark.
I take the bus home from work, and in the front where there are just dim red
overhead lights, I don't need the backlight, even though my 48 becomes
difficult to read.
Basically, note to hp: Buy LCD's from the same company 3com does!

otherwise, what would be the point. if so, is it worth the cost to the 99.9%
of users who don't calculate in the dark? would it be worth the extra power
consumption? gonna add a light power switch? it's a calculator, not a laptop.
i'm all for a more legible display with better resolution. but i don't want
to pay extra for a lighted display that i will never use. in all my years of
using a calculator (41CV from '82 until about '90 and a 48SX since), i've never
said, "i sure wish this thing lit up." however, for those of you who feel
strongly on this issue, he's your chance. design and build a snap-on accessory
light with it's own power source.

Well, I think it shouldn't be a big problem to build a sidelight
with some white SMD LEDs. They could be fit into a very small
border around the display.
