Fx-9750GII

FX9750GII

This model is the international equivalent of the French G35+. Several improvements have been made since the original fx9750G, as it now has 62 kb of usable memory instead of 26 kb, and comes in two main varieties. The earlier model uses a SH3 CPU and has a deep blue case with a white keyboard surround. It's often referred to as a USB Power Graphic. The newer model uses a SH4a CPU, has a white case, with a deep blue keyboard surround. Labeling of this model varies, sometimes being the same as its direct predecessor, or sometimes using the label "USB Power Graphic 2", and it's informally known as the fx9750GII-2.

Budget model

Casio made this a lower cost, function-reduced equivalent to the fx-9860GII, aimed at budget-conscious customers who don't need the additional functions.

Missing hardware

The fx-9750GII doesn't have the hardware for the backlight, and doesn't have the SD card support found in the fx-9860GII SD. Neither of these can be added in. In the plastic packaging, the calculator's often supplied only with the unit-to-unit cable and a set of batteries, so you'll need the right USB cable if you want to connect the calculator to a computer.

Missing software

It doesn't contain the eActivity or Spreadsheet applications. In addition, you are unable to install Add-Ins, as the FA-124 software simply won't allow you to install .G1A files. There's no access to flash storage, no S-V.P.A.M.™ natural input or output, and no vector operations. However, you are still able to program in Casio Basic, and everything else works like the fx-9860GII except for those points.

Upgrading

The OS can be easily upgraded to the OS available for the fx-9860GII. You'll need a copy of the latest fxRemote, a copy of the latest available fx-9860GII BIOS, the USB cable that connects your calculator to the computer, and finally a relatively fresh set of batteries. It's very important you know which model of CPU your calculator has, as this affects which BIOS image you'll flash onto the calculator. Several people have reported bricking their calculator and making it unusable (and unrepairable).

You can check what version of the OS you have already, by checking the Memory application in the calculator. If it has a version string of 2.02.xxxx or later (the xxx's are numbers which don't matter for this discussion) then your calculator has a SH4 CPU. If it's 2.01.xxx or earlier, you probably have a SH3 CPU.
