A small EL panel could easily be made outside the calc to shine on the 
keys. It wouldn't need to be big. Maybe even a small metal mirror in the 
sliding cover. flip it up (it could be hinged) and it would reflect the 
LCD's light onto the keys. You'd just need very reflective metal and 
you'd have two tabs that would stick into two holes drilled in the sides 
of the sliding cover. Nothing special. Wouldn't even need to snap into 
place. The calc would hold it. up whenyou slide it into the cover.
