The response I received noted:

"The problem was that we have a timing problem at the c128."

And the timing diagram needed was:

DotCLK  _| |_| |_| |_| |_| |_| |_| |_| |_
                 _______________
Phi2 =OE_______|               |_________
                   _______
Phi2'   _________|       |_______________
                       _______
Phi2"=WE_____________|       |___________


I hope that helps.
