fx-9860gii-2 brief introduction

[Mjim]

First of all thank you Hlib. I had not heard of C.Basic, but am impressed at it's speed (the sequence function can build a table of 10,000 values of sine between 0 & Pi/2 in 2 seconds for my calculator....that is just madness that wouldn't of been possible without the performance and extra unlocked RAM of C.Basic). Appreciate the power measurements that you did. Would be interesting to see what kind of power usage you would get in C.Basic, considering how nicely optimized it seems to be.

In a way, I prefer the nice contrast of black LCD's on the fx-9860GII/9750GII over the colour display on the fx-CG50 as I'm not particularly keen on backlit displays for calculators (also I've heard the CG50 has SDRAM which loses memory after being powered off for about an hour vs SRAM (fx-9750GII/9860GII/CG10/CG20) which retains it until battery replacement). I would love to see a Casio graphing calculator with a high resolution black LCD (perhaps sporting a pixel density similar or better than the 991EX); or if it is to be colour, a transflective LCD display, so it can be operated without the backlight.

I just discovered that "Execute Time" flag, was trying to figure out how you got that sort of execute accuracy, so I'll post my results on my fx-9750GII (SH3 - 9860GII firmware).
