Add matrix calculations and natural display to 7400GII

Postby Raafat » Tue Jan 10, 2017 12:54 pm

Heyy,

Is 7400GII upgradeable to 9860GII or can be made to support natural display and matrix calculations

If so, how?! I am in desperate need for those two functions and couldn't afford 9860GII

The fx-7400GII has only a 2 MiB flash. The fx-9860GII OS does not fit.

Unfortunately the functions are no replaceable modules.
They are deeply embedded and entangled in the operating system.
If possible at all, you'd need the operating system's source code. But that is far out of reach.
Sorry.

No, the fx-9860GII OS is far too big.
But it's possible to upgrade it with a smaller fx-9750GII or Graph35+ OS to have what you want.

Ver 2.04.0701
What difference does it make?

Ah, sorry then - it's impossible on your version.
You need version 2.00-2.01.

A version 2.02-2.04 means your calculator is using an SH4 CPU.
The fxRemote flashing tool doesn't support fx-7400GII calculators with the SH4 CPU.
And anyway, fx-9750/9860GII SH4 images are bigger and won't fit in your 2MiB ROM.
