Yep, you can't overclock a MkII and keep the SCSI module on it. As soon as I took the SCSI off, everything was cool. I tried a 66mHz crystal, but got crashes. Could be I need faster memory, but I was happy enough with 60mHz.
this is a well-known problem.
CyberSCSI must be clocked with the original 50 Mhz crystal, otherwise, unstability and even not working CSMKII at all.
Ciao
EDIT- someone knows, where could i purchase, a 68060@66 Mhz?
