Another fake Doom run, like the predictor one. This doesn't actually run Doom. Sorry. Meanwhile, other esoteric platforms actually runthe software.

There's the Infocom ZMachine with Zork I-III, Tristam Island, Calypso (Z machine v3 games) and many more which can be run starting from a PostScript file to a pen, a simple FPGA machine, an Amiga, the original Game Boy and who knows what.

If you can port a libre interpreter, you can run it. Old PDA's, Smartphones, JS browsers, Windows 95 machines with Winfrotz, DOS, Raspberry Pies with GNU/Linux, Riscos... There are emulators even written in Perl, Python, Lua, tons of them. It's text based output and the Z machine format it's documented.

I think some Activision games had the the Zork game embedded on their engine as an Easter Egg. As it's an 'easy' task for any programmer embedding it under a fake ingame computer woudn't have been a daunting task.

Maybe I can adapt the PostScript one to Eforth under the Subleq VM, PS' syntax maps slightly ok to EForth...

With Asterisks and some old modules you can even play it over a VOIP client and listen to the output with Flite/Festival/Espeak-nG or any compatible TTS software, such as PicoTTS. The voice input it's done with CMU Sphinx.

Something Doom can't do at all.
