       [Scotty, it is a line eater!!  BEAM ME U.......   ]
       
       If this sounds out in left field, it might be.  This is
       just a wild idea that I am working on. 
       
       I have purchased a S-VHS video recorder recently and I
       would like to hook up the S-VHS output of the recorder to
       my Amiga's monitor (a 1080).  Of course, I can hook up
       through the normal VIDEO connection on the monitor's back.
       However, the 1080 monitor also has inputs for a seperated
       NTSC video signal.  What I want to do is connect the S-VHS
       output on the recorder to the seperated video inputs on
       the 1080.  The recorder is a JVC model HR-S8000U.  The
       S-VHS output is a special four pin connector.  I do not
       know the pinout of the four pin connector on the recorder
       yet (it is not in the manual).  I plan to write to JVC to
       ask them for it, but if anyone knows it please inform me.
       The monitor inputs are RCA type jacks.  
       
       According to the manual the recorder outputs the seperated
       video signals as a chrominance(Y) and a luminance(C)
       signal. The chrominance signal spectrum is normal(?) NTSC
       at 629 KHz.  The FM carrier frequency of the luminance
       signal ranges from 5.4 - 7 MHz (seperated Y/C, S-VHS
       resolution) and 3.4 - 4.4 MHz (normal composite, VHS
       resolution). 
       
       My question, will the 1080 accept luminance signals in the
       5.4 - 7.4 MHz range?  Or, do I need to build some type of
       interface for it, perhaps into the RGB analog port of the
       monitor? 
       
       
       There is also a S-VHS input on the recorder that is a four
       pin connector.  I would like to be able to use this to
       record from the video output of my Amiga(s) (I have both
       an A1000 and a B2000).  Does anyone know how this might be
       accomplished?  I would be buffering pictures into memory
       (5 MB) to acheive a reasonable playback speed for simple
       animations.  This is for fun.  I am not worried about
       getting professional(maybe later) results, but would like
       to use the S-VHS resolution mode of the recorder. 
       
       If anyone has already done this please send me the
       information on the cable and/or interface needed. 
       
       			Thanks,
       				Ray.
