I just modded another Model 1 (VA6) Genesis, and I would like to offer you all the chance to purchase one of the two systems before I put it on eBay.
The first unit I have is a Model 1 HDG Non-TMSS unit with gold-plated audio and S-video connections, and a nickel-plated composite connection shown here:
http://forum.arcadecontrols.com/index.php?topic=106432.0Unit works and plays great. Also swapped out the LED with a brighter one.
Second unit is the Model 1 I mentioned above. I just finished putting it together last night, and didn't get a chance to snap pics yet, but I'll post them if there's interest. All connections are gold plated, but my drill slipped on the composite jack, and it's about 1/8" higher than the audio and s-video jacks. Not a huge mistake, but it's something I wanted to be up front about. Unit IS a VA6 (missing EXT connector, but has the space for it), and sounds fine. This Genesis is in EXCELLENT condition. I didn't swap out the LED on this one, due to it's pristine condition.
Make an offer on either one - once one sells, I'm keeping the other (for now).
This listing will be up for 7 days before I put one on eBay.
