From Byte magazine, Feb 1987, the What's New section (p.38):

"		   Big Monitor Lets You See What You'll Get
		   ======================================== 
The LM-300 monitor from Princeton Graphic Systems has a 15" portrait-mounted
screen that can display a full page of graphics and text, in WYSIWIG format,
without scrolling.  Pixel resolution is 1200 by 1664. Video bandwidth is 160
MHz. Scan rate is 74.63 KHz. The monitor emulates a resolution of 300 dots per
inch (1:1 aspect ratio), making it compatible with many laser printers.  Other
features include 42,000 characters display and support for four shades of gray.
The monitor is attached to a tilt-and-swivel stand. It comes with a 9-pin
shielded cable and connects directly to IBM PC's and most compatibles.
Suggested List Price is $750.                                                 "

I also saw P.G.'s ad in one of the PC magazines (March issue), which is in
agreement with all of the above, and also talks about compatability between the
LM-300 and their 300dpi scanner, and about related software (cut-and-paste
directly in WYSIWYG format).
---------------
I have some related questions:

1. The screen  measures 15" diagonally, meaning roughly 9x12". Resolution-
   wise, we're talking 135dpi (1200/9 = 133 ; 1664/12 = 138). Now, that's an
   excellent resolution, to be sure, but not nearly as good as 300dpi. Did I
   miss anything, or is there really some sort of compression going on?
2. Hercules card, for all I know, supports resolutions up to 800x600, or so. 
   Are there widely available and reasonably priced controllers for higher
   resolutions?
3. Never heard before about the WYSIWYG format -- what is it?
4. The hint about Cut-and-Paste software suggests a format that can be both
   displayed and printed. This is in contrast to the standard TeX approach of a
   .DVI file which must be filtered separately into each output device format.

What I have in mind is a fancy-but-inexpensive TeX previewer.  Did anyone in
Netland, particularly a TeXpert, take a closer look at the beast? Can they
address some of the questions?
