They still make 7400GII's???!!
Yeah, they "revived" their old series from 1999. It is almost identical to an fx-9750GII now, but without USB port, less software functionality and a 2 MB flash chip (no add-in support). The OS is updateable as on all recent models.

Also I wonder if the FX-9750GII and 7400GII that has the SH-4A can be hacked to be turned into a FX-9860GII like we could do with the older 9750GII? It seems to be feasible for the new fx-9750GII, but the fx-7400GII comes with a 2 MB chip only and the fx-9860GII OS is about 2.5 MB...

The new models have the label "USB Power Graphics 2" on them and the design has changed:
I guess, you are mixing something up here. The new fx-9860GII calculators have been around since early 2009. These models were marketed as "USB Power Graphic" and don't have an SH-4A chip and the SD model only supports SD cards up to 2 GB. And the new CPU is now used on the fx-9750GII and fx-7400GII series as well.

So it's much like a Prizm, but with a monochrome screen and a SDHC card reader? Sounds nice. And only 1.5 MB of storage memory for add-ins.

It would really suck if Casio broke compatibility with old programs. It would mean they're going the TI route in some ways (remember OS 2.53 MP and how old Lua programs break in newer Nspire OSes) Would? They did break compatibility. But it's not their fault as they warned their users not to access hardware directly. If you used the official Casio SDK, your programs will continue to work. However, this SDK offers very limited functionality only.

Does this mean that Power Graphic SH-3 FX-9860's will not be able to use add-ins developed for FX-9860 Power Graphics 2 models? If they solely use SH-4A-specific features, then yes. But my hope is that most experienced hackers will make their programs cross-platform compatible. However, does this means old FX-9860G add-ins will no longer run on this new model? Indeed, most add-ins have stopped working. I kinda like the look of the old model, though. Nah! I'm still a fan of the classic fx-9860G SD!

1.) Casio guru Simon Lothar 2.) Just look at the picture: No, they did not change the display.

Can the regular power graphic models use prizm code also? No. The Prizm OS has been compiled directly for SH-4A meaning that new instructions and processor-specific entensions are used. These would cause critical exceptions on an SH-3 CPU. What I mean with "code sharing" is that, for instance, we could use the init code for the Prizm's frequency control register (FRQCR) to speed up the new GII CPU to 58 MHz as well.

Yes, it's true. They now use an SH-4A CPU (without FPU) like on the Prizm. Meaning that it should be possible to share at least some code between both platforms. Also, the new fx-9860GII SD now supports SDHC cards with up to 32 GB of memory (which the Prizm doesn't!).  You can identify the new models by the label " USB POWER GRAPHIC 2" or by the preinstalled firmware version " OS 2.02".

Can't I just flash fx-CG20 software on it? Actually, the fx-CG 10 OS is identical to the fx-CG 20 one.

This is available on the fx-9860G Slim only. It's not part of the Prizm OS.
