Well, we received 4 of Norm's BusinessLand demo cubes in the past 10 days,
just about 30 days after they were ordered.  My office was filled with NeXTs
for a while, and I started to notice that my own MegaPixel (bought 12/89) is
going out of focus!  Also, the new machines have a bluish tint, while mine is
a definite neutral gray.

Now, I leave my machine on all the time, with Gerrit's LockScreen application
blanking the screen, so the monitor stays warm but there are no burned out
areas.  This computer has been moved almost 1000 miles by car, too.  There
are, in other words, plenty of reasonable explanations for the los of focus,
but I never noticed any dramatic changes in the screen focus.  It took direct
comparison with new machines to bring it out.

Have any of you other old-timers noticed your cubes getting fuzzy?  Have you
tried to do anything, like having a CRT repairman adjust the screen?  Has any
linear EE type with an out-of-warranty MegaPixel (like mine) opened it up and
performed amateur surgery?  Did the patient recover?  

Cheers,
Victor
