Another WebAudio based emulator for legacy chiptune music: This time emulating the AtariST – my work was kindly sponsored by PhotonStorm. Here I just ported the existing SC68 emulator to the Web.
update: I meanwhile updated my Web port to the latest version of SC68 and the linked page no longer looks like the screenshot from the original post.
