I tried to respond to this guy's question that you forwarded.
It bounced. I hate seeing email posted to the net titled
"VIC068/VAC068 chip problems"
so I would like to steer him in the right direction.

If you believe the source of your board problems are VIC/VAC related,
I recommend contacting the Cypress FAE office in Minnetonka, MN. They
are very experienced with our VMEbus product line and would be happy
to answer any questions you may have. The number is 612-935-7567. I
would suggest you prepare a detailed explanation of your problem
before you call. e.g., VMEbus features your application supports,
details on the failing bus transaction, timing waveforms, etc. Due to
the complex nature of the VMEbus protocol, the more information you
provide, the better.
