IIRC there are some DIP switches on the frame buffer where you can
configure the monitor type internaly or use the sense pins on the 13W3
connector for recognizing the monitor. In any case: You need a sync on
green capable monitor.

No OpenFirmWare AFAIK, but my /250 switched to serial console when I had
no monitor and no keyboard attached. Maybe you need to switch it to
"service mode" at the front. Be patient. Sometimes these machines need a
_long_ time to POST until they start talking on the console.
