You can, but in normal light it doesn't help very much, you still end
up with decreased contrast over the original. Part of the problem
with the backlight is that with the light comming from behind the
LCD you don't get the double polarity twist, so the pixels aren't
quite as opaque.

I haven't seen the 89, how does its contrast compare to the 86?
(anybody). Just from a contrast standpoint the 86 is the best I
have seen so far, they didn't try to tint the LCD (which is annoying
at best), its nice and clear.

Yep, you'd think that computer and electronics makers would figure
out soon enough that the two biggest (IMO) usability factors in a
product design are input and output. Handheld calcs should have
high resolution, high contrast screens, RS232 serial ports and
decent keyboards (I don't have a problem with they keyboards,
they work pretty well). Analog inputs would be nice too, but not
really necessary for strictly calculator functions. I guess they are
trying to save money and make profit by selling these things as
extra stuff (CBL, graphlink, etc).
oh well, maybe on the next TI calc... At least they provide ASM
support now.
