I remember MAX! The music theory drills that eventually ended up as Java applets on eMusicTheory.com started (a few of them, anyway) as MAX applications, in '95/'96. I helped a music professor develop some of those, then (because we wanted students to be able to practice outside of the music lab, and because I was learning Java in compsci classes) I started rewriting them as applets.
The applet versions even support MIDI input (just plug in your keyboard and you can use it to give answers to the online drills!), but the sequence of Java security disasters will probably spell the death of that feature -- when I drop applets, AFAIK there's no other in-browser way to catch MIDI input; it's frustrating as hell.
