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

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.

seems like an account reposting stuff to get attention to advertise his AI stuff.

People keep being amazed that Turing-complete mechanisms can run any program. ;)

Why climb Mount Everest? Because it's there.
