[Visceroid] could only find overclocking resources online for TI calcs. He spent some time under the hood of his casio fx-9750G plus and sent in a write-up for us. I gave it a quick edit, but here it goes:
I opened up the calculator, which reveals the board with the processor on it,
with the RAM, ROM, CPU and a few other surface mounts visible.
The graphics are underneath and the buttons are also underneath on an underlying board.
The main batteries, backup battery and serial port are connected on the underlying board, and I also have access to them.
