Sun 100U video display Issues

from a couple websites, first... http://sunstuff.org/Sun-Hardware-Ref/s2hr/part3 The standard monochrome framebuffer, found in everything from the first Sun-2 to desktop SPARCs, and the 386i as well. Standard resolution is 1152 x 900 and high resolution is 1280 x 1024; other resolutions (1024 x 1024?) may exist. The very first implementations were TTL-only output levels, or switchable between TTL-only and TTL/ECL; everything since has been TTL/ECL. second. http://mail-index.netbsd.org/port-sun3/1996/05/14/0000.html The line frequency (horizontal scan) rate for the high-res is 89.3Khz while that of the normal monitor is 61.8Khz. The field (vertical scan) rates are almost identical at 66Hz and 67Hz. I presume that the framebuffer is the following 501-1003 "Sun-2 Monochrome Video" Multibus (with keyboard/mouse) DEVICE: bwtwo RESOLUTION: 1152 x 900 POWER: 4A @ +5V if not, what is the sun part number on the board?
