keyword=re: timing shifts
I think the problem with the timing shifts may be due to a
flakey (intermittent) cable carrying the retiming (RT) signal,
or possibly the NIM module that makes that signal. A loss
of this signal would cause exactly the observed shift in T0.
During access we examined this cable and found a bad looking
(worn out) connector which should be re-crimped. I'll ask Jack
Segal when he comes in to fix Fastbus. During access the loss
of RT was not actually observed on the scope.
