Keep in mind that this is written entirely in JavaScript, so please adjust your expectations. The virtual machine emulates a 900 Macintosh Quadra 1991 with a Motorola processor, which Apple used before switching to IBM's PowerPC architecture in the late 1990s. You can also run it on a Windows or Linux machine.
It all works on your Mac as a single, stand-alone JavaScript application.
Thanks to Slack developer Felix Rieseberg, you can now run Mac OS 8 on a 900 Macintosh Quadra 1991 without having to worry about separate emulators and operating system installations. I love that some people have too much free time.
