I think I forgot to mention that the fix for the Combo Boards is FREE, if you
know what to tell the person on the hot line. What they do is match your
symptom to their list. If your symptom(s) match the Z8530 replacement, they'll
send you the kit. Now for what you asked. The problem I was having was garbled
data that went from one machine to the other WITH the Combo board. I think I
also mentioned crashes that seemed to be board related, but I wasn't sure about
that one.
