The newly-deployed Moniterm displays for the RT are sensitive to the
small voltage glitches caused by LN03 laser printers. Those printers
do something that involves cycling a toaster or whatever. When they
do, the Moniterm picture performs a significant shimmy, usually
losing its grip on the vertical hold for one display cycle.
This problem isn't serious, but it is one we should be aware of,
because users will probably report it thinking it is a symptom of
some deeper trouble.
Charlie: I think you probably ought to get this fact back up the line
to the people who build them.
