Gentlemen,

I built the cable 3W3(VAXstation-4000-60) to VGA(Monitor) following the
scheme as follows:

   3W3-A1        ---->  VGA-1   RED
   3W3-A1-gnd ---->  VGA-6
   3W3-A2        ---->  VGA-2  GREEN
   3W3-A2-gnd ---->  VGA-7 
   3W3-A3         ---->  VGA-3  BLUE
    3W3-A3-gnd ---->  VGA-8

However, when I turn on the Vaxstation, system starts the diagnostic test,
monitor starts up and the screen become light-blue for a second as per 
the regular screen-test
but no SRM chevron prompt shows up. I can not get the command prompt on
the screen. I have no keyboard at present so I am using a serial console to
communicate with system prom. I realized that the monitor screen displays
a very dark-green but I can not see any >>> on it.
Does the monitor require a keyboard to start up ?
What am I missing here ?

TIA,
Luiz Regis
