Mac OS 8 running as an Electron app emulating a 1991 Quadra

This is Mac OS 8, running in an Electron app pretending to be a 1991 Macintosh Quadra. Yes, it’s the full thing. I’m sorry.

Does it work?

Yes! Quite well, actually – on macOS, Windows, and Linux. Bear in mind that this is written entirely in JavaScript, so please adjust your expectations. The virtual machine is emulating a 1991 Macintosh Quadra 900 with a Motorola CPU, which Apple used before switching to IBM’s PowerPC architecture in the late 1990s.

This exists now.
