decided he could live without the echo (the board you are referring to didn't exist then).
What no echo on Centaur?? Shame! I would strongly recommend getting the after market board. The cable is not hard to make up if it is missing, as long as you have got the right S&T board in the machine. There is another mod floating around to adapt the SIA to use a different chip, but I have not got around to trying it out as my SIA is still alive...
cheers

Yep, his loss!
I was looking at the other mod too recently. Looks interesting, and the chip used is available. Shame it's not a direct replacement, but it is close.
