Except that the SuperDrive card would use a SWIM chip rather than the IWM.
All this talk about the IWM has raised a couple of questions:
1) Did Apple every fully document this chip and what it can do?
I have looked in the //c Tech Ref Manual (2nd edition) and
the Inside Macintosh (Vol 1 or 2) and got a little info but
not much.
2) Did Apple ever sell them to 3rd party manufacturers? What does
the Chinook //c HD use to talk to the Smartport bus?
