You're correct. All the hardware says 2830 also. The only piece physically that's different is the sticker on the front.

It seems the hardware ID we're actually looking for isn't stored on either of those 2 chips?

BTW- I saw this video:

He's able to call the version numbers up in his terminal window. Is this a route we should consider also to try and modify that?

The AT24C512 is nearly empty. There are 64 bytes of data at 0xc000 and 0xe000 and that's it. Maybe this flash is where the user defined system settings are getting stored in.

The spec sheet says "Built-in Storage Internal 100 LCRZ instrument setting files, 201 times test results" - maybe that's what those 2 chips are.

nctnico:
That is possible. There is also an internal EEPROM inside the LPC1788 which could have the model ID inside. Only way to find out is to write software into the chip that can dump the internal EEPROM.

That's beyond my skills. Anybody else? lol
