I don't recall seeing any mops around when the CE's replaced a board
on the 1100/90's.  They were not "hot-swappable"--but nobody had thought
of _that_ as a good marketing drool.  We had "redundant" equipment and
took the broken one off-line to work on it.

Be interesting to know where that came from.  Particularly when you consider
the "liquid-cooled" versus "can't do it" costs.

Had your finger on an operating LASER lately?
