Hi,

I just received this message from Patrick at Purdue stating that:
------
DEC's version of a 3W3 connector has the red and blue swapped from IBM's
version.
Just re-wire it to connect A1 on the 3W3 to 3 on the VGA connector, and
A3 on the 3W3 to 1 on the VGA connector (and swap the coresponding
ground lines).
-----
So,  I swapped the blue and red cables and the colors show up correctly
on screen now.

Thank to you all.
