  According to the Sun FE handbook, J800 pins 15-16 is a jumper
location that controls the resolution and behavior of the 3/60's
onboard frame buffer.  If the jumper is in, it forces 1600x1280.  If
it's out, it auto-selects if used with video cable p/n 530-1359 or
530-1336.  If it's out and you use a different cable, the resolution
is 1152x900.

  I checked the 4/200 pages of the guide and found nothing about a
4/200 board with an 1152x900 frame buffer.  If there was a version
produced that supported that resolution, it's not in the Sun FE guide.
