How many square inches of display do you need to drive?

The EL drivers that I sell with my backlight kits might
do what you need, typicly these are used to drive about
5 square inches (a TI display), but they will handle up
to about twice that.

Just the inverter is $15, $28 for a full kit, including
EL film for an 8x series calc (92's are a bit more).

I dont recommend backlighting for the 83+ and 89, due
to a difference in the LCD construction, but I'll sell
kits for them if anyone wants to try.  Ain't my fault
if ya' bust it. :)
