Nope.

UPDI used on Atmel micros on Anduril capable flashlights uses a single line for debug and flashing. Much earlier than that, Motorola/Freescale/NXP Coldfire, S12, and some other MCUs used BDM which was also a single wire protocol.

If you want to flash a newer Anduril to this light, look here for hardware and procedures to use those pads.

That's exactly what they are, but instead of connecting to a VAX at the other end of a modem they talk to a shell attached to a pseudo terminal device on the same machine.

It's not known to be a backdoor, but it's a juicy attack surface that customers are largely ignorant of and provides little consumer benefit. If I were an NSA employee and my boss handed me a blank check to develop a preboot exploit for Intel PCs, I'd start with IME.

Slackware is the 50 year old percolator in the break room of the DMV.

Before trumpeting you're obligated to yodel "RIIIICOLAAAAA" through a cardboard tube, much as a father must clack tongs before tending a grill.

It's dependent on the manufacturer to decide if they want a black box system management processor, what architecture to use, and what it will be responsible for.

The Raspberry Pi SoC uses the video accelerator processor (VPU) for bootstrapping the ARM CPUs - effectively making the ARM a coprocessor to the VPU. The config.txt and *.elf files you have to put on the SD card are the OS for the VPU and bootloader for Linux that gets loaded to the ARM cores.

That had not occurred to us, Dude.

But don't take my word for it.

A real life series of fetch quests on acid. Myst and SCP had a lovechild, and it's a four story tall warehouse in Denver.

If you ever have the chance to use an old Apple II computer, run a text mode program, wait til the owner is looking in the other direction and turn the power off and back on quickly.

For about a second, before you hear the loud BOOP and the screen clears, you'll see whatever was on the screen just before you powered it off. But a few characters will be corrupted. Try it again, and wait a half a second longer than before. More characters will be corrupted.

For that brief second you're looking at the contents of the video RAM, then the ROM (Apple called what we call BIOS now "ROM") clears the contents and puts up the familiar text banner. The longer the power stays off, the more the contents of those RAM cells decay, and any bit flip will show up as a different character at the corresponding location on the screen.

On a side note, there was an article in the early '80s in Circuit Cellar by Steve Ciarcia showing how you could make a rudimentary digital camera by prying the top off a DRAM chip (some were ceramic with metal lids, or just metal cans) and adding a CCTV camera lens at the right distance. Light can deplete the charge in DRAM cells even faster, and by writing all 1s to the memory, exposing it to light, and reading back the contents, you could get a black and white image of whatever's shining on the chip.
