Yeah basically you get the idea...... can rule it as an ArcadeVGA fault without ruling out the cable itself first.
Kevin, here's the weird part. I tested both the cable and the card, both tested good. Connected it all back up and all is working, including the red color, in the appropriate way.

I don't know how to explain it but there it is.

My concerns now are 2 fold.
1) I pray that just as abruptly the red doesn't go back to the way it was.
2) It appears that I need to adjust the geometry of my monitor, at least the bottom right corner is out of line with the top right corner and on the white and red boxes test screen I can see a little red above the upper right corner box. Looks like I'm not done yet

any advise on either or both issues ... anyone

... and I wanted to express my gratitude to everyone who read this thread, especially those who offered such sage advise. Thanks!!!
