[Ham-Mac] pinout guide for iMac.

[David Anderson]

Hi again Louis,
			Well well, very interesting indeed, I knew that the USB powered 
speakers with the Cube had an external amp, but did not think that the 
new iMac speakers had! - I assumed (wrongly) that the small plastic 
interconnect was just that a purely passive connector

Why on earth did they do that? - Wouldn't it have much simpler to have 
the amp inside the Mac? - Anyway, wonder why you need the connections 
for the speaker socket? - Does the headphone socket not do what you 
want? - For interfacing to a radio?
