I want to thank all of you who responded with many helpful suggestions.
And as usual, it appears that the original understanding of the problem
did not lead me to any reasonable conclusion. The bridge was not a factor.
In particular thanks to 'Merle'

We sent some folks in the know out to investigate the segment with the HP
on it. It turns out that the DEC lanBridge and all the hosts on the
second segment had nothing to do with the problem. What follows is a
more detailed picture of the problem and the "fix".

. == Thinnet
C == BNC connector
* == Fiber
? == no connection
No one seems to know what the extra + was doing connected via 1 foot of
Thinnet at location 1. However, 1 was swapped with 2 and things started
to work. It was decided to initial #2 with "NG" and remove it from the
configuration as follows:
