Greeting from the first day of 2014!
The very first Graphing Calculator with a Color Display – CASIO CFX 9850 Review
Introduction
It has been 27 years since the first graphing calculator – CASIO FX-7000G – was invented. Today, all new graphing calculators have color displays. Believe it or not, back to 1993, there is already a color display graphing calculator: CASIO CFX-9800G. The one I am going to review, it the CFX-9850GB Plus released in 2002.

This screen was manufactured much earlier than the last screen, so early that it is an STN screen instead of an FSTN one. But I would say, still a good one, I just like screens.
#LetsDriveLCD [9] – GPM675A0
Just a nice-looking 320×240 controller-less LCD. Got it at a very low price ($0.7 each). I am always thinking about making something around it, but it just doesn't happen.
