Beyond how cool this is, I appreciate the sorry part :)

This running MacWord+MacExcel in 1997 would have prevented the dystopia from coming true. (Of course, the dystopia is necessary to even conceive of doing this!)

Now put down the keyboard, raise your arms slowly and back away from the NodeJS interpreter. ;)

This made me so happy. Thank you for doing it!

Love playing with this! Thanks for creating it. Fun to see my name again in the secret About box credits. :)

This is amazing. Thank you. Now to find a few of my favourite old games!

how easy is this to get running in an actual browser, rather than Electron*? I want to host some Hypercard stacks (some of which need Quicktime support, hence colour Mac emulation).

It appears to use this as the emulator: https://jamesfriend.com.au/basilisk-ii-classic-mac-emulator-... You can just directly use that instead.

James Friend is the one who got the C compiled with Emscripten, and as long as you're able to serve an entire disk image from a server (and don't crumble under the bandwidth), a browser is good enough.

Electron is only here to ensure that state is saved (save a game, quit the app, start the app, your save game is still there) and to make the mounting of disk images and transfer of files from your local machine super easy.

Hey

This is so cool!

this is one of the best posts of mac history on hacker news in a while someone should try this on their developer arm mac

Cool, but isn't this problematic? Maybe you should have the user provide a ROM

That's indeed probably a bad idea if the author wants the repository to last, embedding unlicensed content is always a risk. Morally I'd argue that it's absurd that such old software isn't in the public domain yet, but legally it's pretty clear that this can't be redistributed freely, although I doubt that Apple is likely to enforce it.
