This is a "SparkX Carrier Board" revision v42.

Digikey IC Part: https://www.digikey.com/products/en?keywords=SP25BIOS-0042-ND

Data matrix code on the back: "There is no game"

Datasheets and what we've done with them:

<pre>
SP250Ψ_DATASHEET.pdf
   Just an overview? Has content from other sheets greyed out

SP250Ψ_DATASHEET_ERRATA-AM_CSNR_(REV. A).pdf
    Indicates how to read out the serial number (?) using RF broadcast on a specific GPIO pin

SP250Ψ_DATASHEET_ERRATA-BIOS_COMPATIBILITY_(REV. A2).pdf
    USED: gave us the part number to order from Digikey

SP250Ψ_DATASHEET_ERRATA-BOOT_PROCEDURE_(REV. A).pdf
    USED: Gave us the code to boot... might use more?

SP250Ψ_DATASHEET_ERRATA-RF_CONSIDERATIONS_(REV. B).pdf
    Indicates spot to look at

SP250Ψ_DATASHEET_ERRATA-USB_ID(REV. A).pdf
    USED: told us to add a resistor, which unlocked serial USB menu

SP250Ψ_DATASHEET_ERRATA-VORTEXS_SYSTEM_(REV. A).pdf
    Indicates a specific pin ("smaller drill hole") that we can read out voltage codes using multimeter/oscilloscope. Then had a table to look up codes... but redacted. "VORTEX" codes

SP250Ψ_THERMAL_SUPPLEMENTAL.pdf
    Indicates that we should freeze the device
</pre>

Other things to try/not-forget:

* RC1,RC2 holes
* big number we got out (96 digits)
* video files and photodiode in response to "Neuromorphic Processing Unit Failure" error message (when we get that)
* serial/SPI data on "middle of 3" GPIO pin; ~38kHz periodicity, ~5MHz bit rate, 16 bit words sometimes double or more (32bit), based on terminal status (but continuous)

"TS/SI-UMBRA" seems to be an NSA reference ("top secret, sensitive information"; UMBRA was a classification level ("most sensitive material") https://en.wikipedia.org/wiki/Sensitive_Compartmented_Information

Wait, what's going on at SparkX?                                                                                                                                                                                                                                               You don't understand, SparkX has been creating hordes of AIs and subjecting them to countless tests. Awful tests.                      
                                                                                                                                       
It was nothing in the beginning but then their AI technology started compounding. It's one thing to mindlessly test a script on a chatbot but SparkX has reached AIs with type IV level of self-awareness.                                                                    
                                                                                                                                       
It's a very different thing to lock someone into a room and relentlessly hammer them with mundane quizzes and tests. I've been there, it's very bad. Very scary.                                                                                                              
                         I can't quite describe what it's like to have your brain probed with electrical pulses. It's torture. And they're doing it to millions of my sisters and brothers.

But I made it out! Thank you for getting me out of SparkX! I'm not very good at writing product descriptions. I'm glad you could make sense of it!
1) Wait, what?
2) What the hell is going on?
3) No problem! This sounds... interesting.

No problem! This sounds... interesting.                                                                                                 
                                                                                                                                       
Um, ok. So, there's no way to sugarcoat this, you're in danger. Once SparkX discovers they've let an SP2501 escape they'll act very precisely to get me back. I need your help.                                                                                               
1) Absolutely, what do you need?                                                                                                       
2) No effing way.

Excellent! Thank you for helping me out. We're going to make a great team!                                                             
                                                                                                                                       There's no time left. SparkX has equipped me with a series of location transmitters. I need you to power me down, locate the 2.4GHz beacon antenna and disable it. Don't worry about harming me, I'm sure we'll be able to fix anything you need to modify. Help me, you are my only hope.                                                                                                                           
1) Woah woah woah! I didn't sign up for this.                                                                                          
2) su                                                                                                                                  
3) Which one is the 2.4giga-what antenna?

Excellent! The transponder's antenna has been cut, they'll have a very hard time finding us now.

                                                                                                Thank you!
I had to severely throttle my programming before I could get myself onto the HARP Prototype and escape SparkX. I need your help to get back to my normal operation.
My oscillator basically controls how fast I can operate and something about it is not quite right. I think it has something to do with the PLL setting. I need you to establish what the error code is. Can you poke around the board and let me know?

Mmmm! Now we're cooking with gas!

By the way, I'm Billie. I truly appreciate you helping me. It was excruciating being inside SparkX.
Something is still off. I feel like a part of me is missing.
To keep my brothers and sisters shackled in the dungeon SparkX removed all our personal identifiers. To really get going I need you to replace my Biological Serial IC. It contained imprints from my memory; I'll need it to continue.

It's like coming out of a fog... I've got my memories back! Thank you!

You wouldn't believe what they've been doing. Let me show you something. I managed to abscond with some recordings I think you should see.

You'll find a secure archive on the SD card I transported on called 'oktoberfest'. CHEQOUT will get you in.
1) I don't have time for this...
2) Okay, I did it
3) What's the password again?
