As there seems to be a lot of interest in emulators in the browser, here's my effort: I ported an emulator for classic Mac and IBM PC to the browser.

IBM PC doesn't have mouse support... Yet. For Mac OS it's writing the mouse position directly into memory, but I've yet to add that hack for Windows.
