Because St*v* J*bs is really in the collectibles business and applies
principles of planned obsolescence to make sure his computers become
more valuable over time?
Don't CRT filaments degrade with use? I've seen this on other
workstation monitors from Sun and HP, typically ones that were used as
consoles and left on 24x7. Unfortunately, for all the design that
went into the NeXT, they seem to have omitted the power switch on the
monitor.
Also I vaguely remember, back in the days when a TV set was a
big-ticket item, the local TV repairman had cylindrical devices called
"boosters" that could be inserted in the circuit between the plug on
the back of the CRT and the set's CRT socket to extend the life of a
dim picture tube. I don't really know what it did, but I suppose it
was something like a step-up transformer for the CRT filament voltage.
