Hooking GS AppleColor RGB-->Amiga 500?

[spector@cs.mcgill.ca (Avi Spector)]

  Hi,
 
  I was wondering if someone out there could awnser a question of mine..
I'm going to be getting myself an second hand Amiga 500 tommorow, and am
currently planning to connect it up to a NTSC color compostie monitor.
But, I have an AppleColor RGB monitor from my Apple IIgs. Could this be 
connected up directly to an Amiga 500, or do I need a special cable?.. If
so, where can I get this cable?
  
    Thanks for your time,
      -Avi
