Connect the SYNC cabel via a 560 Ohm resistor to the green signal. This
is easy to do with a BNC-T plug like the ones used with 10Base2
ethernet. I used this cabeling scheme to drive sync on green Monitors
with PCs and a SPARCstation 1+ with cgsix. But be sure that the monitor
can sync to the H-frequency of the Sun. Usualy 61.8kHz or 71.7kHz. The
frequency depends on the type of framebuffer and the monitor-sense bits
on the Sun. See http://www.iaehv.nl/users/leibbran/sunmon/sunmon.htm=20
