	The Seiko CM-1430 is a high resolution VGA monitor that also
has a 8514/A compatible mode (1024x768 interlaced).  At the intermediate
VESA mode (800x600), it's ability to display properly depends on the
monitor card.  I had previously reported that cards by Paradise or that
use the Paradise chip, produce an 800x600 mode that rolls vertically
approx. 3 times every 2 seconds.  It has since been pointed out to
me that one can adjust the vertical hold (which involves removing the
outer case, and requires a watchmaker's screwdriver and a steady hand)
to stop the 800x600 rolling, while still preserving the vertical hold
at lower resolution modes (although it's quite a fine adjustment).  I
have seen such a monitor in operation (that is, a Seiko CM-1430 serially
displaying CGA, EGA, VGA, and VESA modes, back and forth with no problem),
and plan to do the adjustment on my monitor just as soon as I find a 
screwdriver small enough, and overcome a little uneasiness I have about
printed circuit boards, and high voltage capacitors in close proximity.

Everything's different. Nothing's changed. Well, only maybe slightly rearranged.
