Is there a writeup somewhere on how it works?
Is it turing complete, runs actual linux binary through wasm or something
edit: went to tweet RISC-V emulator in PDF

Just like Doom-in-a-PDF, this is in equal measure incredibly impressive and utterly horrifying that it's possible.

PostSscript files came from the same company in the 80's
-Adobe- and with GhostScript and zmachine.ps you can play Zork I-III, Calypso, Tristam Island and the rest of propietary Infocom text adventures on it with ease.
What zmachine.ps does is to emulate the ZMachine VM in PostScript and display the output to stdout/console.
And if it werent for the PS stack limitations for sure you could emulate Linux under Risc-V.
Heck, you can emulate old RISC Linux' syscalls (enough to run static binaries) in Perl without ever calling to C bindings, not even once.

It's also all over LinkedIn. It's all just kind of super dumb imo. One of the worst offenders of note was this security person's ad-riddled regurgitation of it that they promoted on LinkedIn:
When I protested about their shitty website shoving ads down my throat, the answer was - I'm paraphrasing of course, but something along the lines of - of course I need ads! I have to cover the cost of my shitty WordPress site (and what are you even thinking to question that!!?? You outta ur mind or somethin?)
I felt like I was indeed stuck with her in 2010 after that...
