   The adapter was called the Video 7 RGB Enhancer and it actually sent out 
RGB signals as evidenced by a demo disk which came with the unit. 
Unfortunately, that was the only RGB material released for the non-GS line. 
   Everything else puts out no better than double hi-res and the RGB  
adapter makes no difference in picture quality than the phono jack.  
(Actually, regular composite video color images become terribly outlined 
and blurry...I have a Video 7 and did lots of tests with almost every  
possible signal source I could think of). 
   If someone had put out a picture viewer (like the SHRView of the GS)  
that could read super hi-res or 3200 color pictures on a IIc or IIc+,  
then a Video 7 would be great. Other than the demo disk, there was no 
other after market support for RGB for non-GS Apples. 
   The Video 7 adapter of the future may very well be the Second Sight 
card for the GS unless third party manufacturers jump on the bandwagon 
and bring out corresponding software. I don't believe the Second Sight 
upgrades existing GS software to the new plateau.
