Hi,

Thanks for you tip, it worked!  In order to attempt your tip, I made
surgical operation on _the adaptor_ to cut Hort sync line(seems Vert
sync line was accidentally connected to VGA pin 14, because it was not
soldered, however the cut end wasn't processed and contacted with pin.
Probably somebody in R.O.C. didn't checked it up before shipping, I
guess.)
Anyway, now I'm installing NetBSD onto classic via NFS to say good bye
to Solaris.  ;-)

Thanks Tsutsui-san and other guys for your help.
