[comp.sys.atari.st.tech] Nec 3D and Mega 2

rick@jpusa1.UUCP (Rick Mills) (09/14/90)

	I've just sold my 386 system and picked up an old
Mega 2 and have tried to connect my Nec 3D monitor to it via
diagrams and a few suggestions. Right now I have something
that kind of works - The lines are connected thru 32 ohm resistors
on the color and sync signals, which works, but there's a shadow
on the text and a bright border on right edges that makes everything
look rather fuzzy and is a strain on the eyeballs... Almost like
the cable isn't sheilded properly, tho I know it is. 
	Anyone have any ideas? Could the signals be crossing over
in the cable? Do I need a lower capacitance cable? Higher resistors?
The signal is at about .6 volts now, if I go lower it gets pretty
dim on the screen...
	Thanks for any suggestions !
	Also - has anyone used the Omni box with the Nec 3d? Does
it work? Maybe that's the easy way out of this...

>ricEMOVE THE RESISTORS! I also have a mega 2 and 3D, have never needed or

used resistors. Suggest you use the GEnie article (or similar) for the

Multisync 2 (as I did) and extrapolate to the newer 15 pin HD connector,

this has worked out VERY excellent for me, and my little gray box also

has an audio port (and video, if I ever hack in an RF modulator).

Luck.
