Calcuscribe LCD

I thought I'd have a look at the LCD panel of the calcuscribe.

The LCD front:



The LCD back, with a bunch of SEC KS0086 lcd driver chips.




Closeup of a KS0086 chip.




The Tianma TM48064BQ board (480x64).



There's a small variable resistor on the LCD board to adjust the contrast but it doesn't seem to clear up the mess on the display, just making it darker or lighter.
