In contrast, I am saying that writing output to ANY tape, even a different one, is still an acceptable Turing Machine.

Unless the machine has at least one tape it can both read and write, then I don't think it can be universal.

Ping me when you've caught up to the current discussion (i.e. after you've bothered to read all the answers to questions that you are repeating right now). We're up to at least Post #678, btw...
