Look at the picture. I don't know what are the consequences.
But if you guys know there is an EEPROM or FRAM inside, as I've previously said, maybe the solution is there and we could try changing there.

I'll try to see if I can get a dump in the next few days.

There's a C64TA FRAM, I think another chip says 45db321e, I think the 74hct138d is CMOS. I'll pop it back open and get a clearer image of that section.
Can you tell us how to get the info from the chips?

Hi Josh,
thats not trivial. I just took a quick look at the C64, thats a I2C FRAM, 8KB (which is very small).
I suspect this is being used to save configuration and other data.
The 74hct138 is a CMOS decoder and irrelevant.
I have a J-Link Pro, if it can read the FRAM I will get the contents.
The other FLASH chip someone mentioned is SPI, so that I should be able to read as well.
All I need is time ;-)
Cheers,

Here's that section of chips:

Thank you Josh.
So, the memories are:
1 x B85RC64TA, 8KB, I2C
1 x Atmel/Microchip AT24C512 (64KB EEPROM), I2C
2 x Adesto 45DB321E, 32Mb "Data Flash", SPI
I think I should be able to dump all of them ....
Cheers,
