I know, this subject just went around a short time ago but I never did
see the final verdict ( maybe this should be put in one of those
frequently asked question postings like comp.unix.questions).  From
what I gathered before, there is some way of getting NTSC from a Mac
II if you make your own cable and get some special utility program.
Where can I get the references for this, has anyone tried it, does it
work well?

Also, I have an analog RGB color encoder, would this work and would
this be better?  Even with an encoder, I still think there must be
some problem with scanning rate and synchronization, is this what the 
utility program is for, to change the scanning rate and
synchronization to NTSC compatible?  My color encoder can also
superimpose the RGB on a video feed.  Does anyone have experience
doing this?  How do you get some parts of the RGB signal to be
transparent to the video signal underneath?  I'd really like to hear
from people who have actually tried this.  To keep from bringing up
the same old discussions over and over, I'll summarize any e-mail
replies that I get (If I get any! Sometimes I wonder if my postings
ever make it out to the net.)
