Hello All, I have a question that I am sure this list has seen before, but I did not see the answer as I looked back over the archives. I have a Digital Audio 466, which is of course a single processor. My loving wife has said she'd like to give me something for the computer for Christmas. Yeah!! Oh, sorry. Anyway, I see adds for processor upgrades from Powerlogix and others that mention both single and dual processor cards. Can I use either of these in my box, or must I stay single since the original box was single? Thanks, Randy
