I have a standard text terminal so I don't need to have a serial until I bring up Open Windows. But how can I get it to use 1000x1022 anyhow. It seems that when it start up it is at 1280x1024@76Hz probably because of the sense lines. If I am able to change the sense lines I could probably set it to 1152x900 according to this table: http://pinouts.ru/Video/SunVideo_pinout.shtml But it would probably hard to do it without some kind of adapter or surgery to the cable. The 1000x1022 resolution is not on the list so I doubt that I can force it into that easily, or? And 1000x1022 is a really strange setting anyway.
