Please please please let me know if you do anything with this, I have a
beached quadra 660av and I'm dying to futz around with the cool stuff
inside (esp. audio).  I'm relatively proficient in 68k asm so I do have the
capability of helping :)  I told Colin a while ago that I would have a look
at the sound driver on it but right now its hard drive is in my new 7200 :)
So if you are planning to do something with the AV mac let me know so i can
reformat etc.
