   More on our PSN problems:  it seems that our ECU link to MILNET PSN 57
was loose at the PSN end; tightening the cable fixed the problem, at least
temporarily.  A short while later, our link was again down.  I fiddled
various things under the direction of the NOC, but nothing seemed to help.
They told me it was a software problem on our end (and I argued loudly,
'cause the software hasn't changed in an eternity), and they finally
suggested going to our backup ECU.  We plugged in and powered up, and all
seems well now.

   Our PSN problems were likely caused by hardware problems with the first
ECU, but things behaved so strangely that I won't be convinced of that until
some hardware guy verifies the ECU failure.  Strange...  but probably
unrelated to the problems others are having.
