fix available for 19" mono Sparcstation frame buffers

[Paul Eggert]

Sun now has a fix for the display glitches afflicting many early 19"
monochrome Sparcstations reported in Sun-Spots in late September.
Apparently it involves adding a resistor to the frame buffer to cut down
noise affecting an output register.

If you have a 19" mono Sparcstation, you might want to check for this problem
before your warranty runs out.  Here's how.  Put just the following lines in
your ~/.sunview file.

	cmdtool    -Wp  641 848 -Ws 511  52
	shelltool  -Wp  569 438 -Ws 570 427

Start a vanilla 4.0.3c 'sunview'.  Move the mouse cursor about two inches
southeast, so that it enters the shelltool.  Wait for the shelltool's
border to darken.  If you you see a series of 14 glitches running in a
narrow horizontal band about an inch from the bottom of the screen, your
Sparcstation has the problem, and Sun should replace your frame buffer.
