As someone working on something in an adjacent space, this is super cool.
Have you ever heard of MartyPC? I think you’d find it pretty interesting as well. It’s an IBM PC XT emulator that supports a bunch of essentially 8088-based systems, and it runs fully online.
They did a lot of benchmark testing with some really iconic demoscene productions, and the results are fascinating. Definitely give it a try if you haven’t already, the WebAssembly version is particularly impressive.
