Used the emit and it certainly made it look better in monochrome mode.
Where do you get this information, just lots of experience?    Is there a book
I should on the lookout for?
Most the time the sparcstations are running with the screen off, I just really
like amber/green phosphor displays for text information.
Video out from my sparcstation 10s don't work with my VGA to TV adapter, I'll
have to come up with something a little fancier if I want have to have this
Or I have a monochrome monitor connected to a PC connect to the SPARCstations
via COM.   This is more the direction I am going now also my PC takes awhile
to boot up, although most of the boot up time is just the start up RAM check.
