Wouldn't an implementation of the DOS API basically fit on any modern microcontroller these days?

  You mean the X86 BIOS? No.

    There is already a working PC emulator for ESP32, and the 86duino is a thing.

      Unusable for near real time tasks DOS did.

        The equipment I have is doing some real-time image processing on a 2000 Hz video stream (it extracts head/eye positions for vision research). I'm sure there's some sort of "microcontroller" that can do this, but an Arduino isn't it. If they had massive volume, I'm sure an ASIC could do it too, but since it's a niche application, an COTS x86 might be near the sweet spot of price/hassle.

        How so? The 8086 emulated on ESP32 is faster than the real one.

        "Real time" does not mean fast. It just means with guaranteed (or at least predictable) performance.
