But does it run Doom?

The MCU only has 3KB of SRAM so probably not. I think you need at least something like a Pi Pico or an ESP32 for that.

Huh. Hadn't looked up the original specs in... Ever? Idk. Operating system: MS-DOS 5.0 or higher Processor: Intel 486 DX2/66 MHz or equivalent RAM memory: 4 MB Hard drive: 10 MB free space Sound card: compatible with Sound Blaster

Looks like you are correct without an upgrade.

Ionescu decided to use the chip’s ability to handle the old Serial Line Internet Protocol (SLIP).

With it, he turned the unit into a very basic 56K modem equivalent. He then added uIP 0.9 code to enable TCP/IP communication and web serving.

Hah, cool. I was wondering if it has WiFi, serial stuff makes more sense.

The ecig waste is tragic though.

The question is why a disposable vape needs a high performance 32-bit 24 MHz ARM MCU. What exactly does it do that can't be accomplished by an 8-bit microcontroller.

Reminds me of a great story about a toaster
