ANSWER...
 
I have a Commodore 1084S connected to my Apple //GS.  I got the monitor
cheap and hooked it up myself.  It works as good as any GS monitor
available from Apple.  To make the connection, you'll need the following.
 
Analog RGB monitor cable to hook up to the Amiga 500
D-Sub Male 15-Pin connector with pins and solder pot contacts
Soldering Iron
Solder
Solder Soaker or a Solder Sucker
Heat Shrink
Heat Gun
Wire Cutters
Wire Stripper
Circuit Tester
Small Phillips Screwdriver
 
You may also want to get the connector casing, I don't have one, you
really don't need it. One other thing, it would help if you had a
third hand...
 
Remove the 23 pin connector from the monitor cable. You may want to
use a hammer to remove the silver Commodore connector case, then again
you could use the small phillips screwdriver. In anycase, you won't need
the Commodore 23 Pin connector or the casing.
 
 
THE PIN ASSIGNMENTS...
 
On the //GS RGB Monitor Port                  On the 1084S ANALOG RGB In
       PIN NUMBER                                     PIN NUMBER
 
           2..............................................4
     (Analog RED)                                   (Analog RED)
 
           5..............................................1
     (Analog GREEN)                                (Analog GREEN)
 
            9.............................................5
      (Analog BLUE)                                (Analog BLUE)
 
            3.............................................2
     (Composite SYNC)                            (Horizontal SYNC)
 
            1.............................................3
    (Signal GROUND Red)                               (GROUND)
 
            6.............................................3
   (Signal GROUND Green)                              (GROUND)
 
           13.............................................3
    (Signal GROUND Blue)                              (GROUND)
 
            4.............................................3
     (No Connection)                                  (GROUND)
 
 
*** ATTENTION:
 
Although there are six pins on the Commodore RGB connector,
DO NOT hook up Pin 6 (Vertical Sync) to the GS 15 Pin connector.
Just chop it off.
 
If you don't know what to do with the soldering iron and heat shrink,
find someone who does.
 
One other thing, take a 4 inch piece of 1/2" masking tape and lay it
over the word Commodore on the front of the monitor.
