   I saw an add by Pratical Solutions for a RGB to composit video adaptor.  I
have also heard of a genlock device that takes in any video signal and locks 
it to another.  I forget the name, but I will get the details.  As I understand
it isn't that expensive (less than $1000, I think) and gives better results 
that the cheap genlocks that are normally used for Amigas.  Note that the Amiga
has a more flexible external video sync control than the ST.  If all this is
true, it would give the ST a much more flexible genlock device than just a 
genlock designed for the ST.  One could genlock a ST and Atari 800 for example.
I try to find out the details and post more later.  I think it is much better
to try and genlock the signals rather than genlock the computer.
