A piece of info that you might find useful. My post-run analyses have
been complaining since about a month for a stop master problem in SM3.
I had the chance to look at it today. SM3 STOP MASTER has never been
the saniest of all stop masters. Since DEC19, 1996 (RUN 13217) it developed
the habit to give freaked-out time words for the trigger secion FOR THE
FIRST EVENT in every run only (there have been 35 runs so far with this
symptom). Nothing really dramatic. Since this module occasionally gives
fake CSPAM latches also, we'll substitute it with the spare (remember this
spare lacks the latching of one TOHM face) next Wednesday. I'll have a look
at my code just to make sure it's not a software bug. If you're looking at
the data, drop me a line if you see/don't see this.
==>>Latest run with this symptom is run 13408.
==>>I remind everybody that as long as we don't receive NEW SPARE ACTELS FOR
==>>THE SPARE STOP MASTER, this module will remain not-perfect.
Finally, the card servicing 2W08-2W14 was replaced today (run13409).
After checking the warnings in Ed's log file, Paolo and me scanned a few
events in previous runs where we saw clear oscillations.
A presto,

Here's a typical event with the SM3 problem:
