Thanks Billy.
Very helpful as I obviously didn't have the complete status.

Thanks Matt and John for your input. You have provided needed
guidance for on the performance of copper cables. I may well give the
Gore a try, I have no objection to paying less. I do wonder, though,
if our good experience with 3 m lengths might be related to our use of
Fujitsu (??).
Based on testing with iBob - F Board I strongly recommend WL Gore over
Fujitsu cables. Fujitsu were completely unacceptable.
Correct, we do NOT trust 3m copper cables for iBob-BEE2.
I don't have a good qualitative number to provide for the failure rate.
As an obscenely crude guess,
1 failure
Hi all,
The heat problem is very familiar, 25 years ago I was working in a big
project and demonstrated that similar problems went away when you cooled
the chip with freon. There was a racing condition somewhere, NEC admitted
it six months later. There is a funny story involved, the chips
Have you seen the recent writeup @ BWRC ?

For copper cables we, ATA, use WLGore cables

(I have re-read a prior thread from early May on this topic involving
John, Matt, Jouko, and Francois, however the sourcing information was
from 2005, and the applicability of the information to our situation
was not entirely clear from the conversation. Also perhaps more has
been learned
