[SunHELP] Sun Video

[Kenneth Dunn]

Having never used a Sun Sparc with a keyboard and VDU attached to it I'm 
wanting to find out how to work out what video modes a system supports so I 
get a monitor for it.

I have a sbus card:

has the following markings:

sticker with FCC ID: gwvtgx1m
on PCB: 270-2922-x04 rev 01

ICs of note with these markings:

Bt Bt458LPJ135 / RAMDAC
LSI   L1A9765   ICFAA  CH02768

Computer in question is an Ultra 2.
