Hello Roy,

This is the pinout for the video connector of an Amiga 
500/600/1000/1200/2000/3000 and 4000.  I got it at 
and the connector is a ?/%$?# DB23, yes a DB23 male and I don't know where 
I can find one.  I can hack my A2000 to add it an other connector to test 
the RGB to VGA
adapter and I'm willing to do it but I prefer to use a DB23 if I can find one.

Pin     Name            Description
1       /XCLK           Extern Clock
2       /XCLKEN         Extern Clock Enable (47 Ohm)
3       RED             Analog Red (75 Ohm)
4       GREEN   Analog Green (75 Ohm)
5       BLUE            Analog Blue (75 Ohm)
6       DI              Digital Intensity (47 Ohm)
7       DR              Digital Red (47 Ohm)
8       DG              Digital Green (47 Ohm)
9       DB              Digital Blue (47 Ohm)
10      /CSYNC  Composite Sync (47 Ohm)
11      /HSYNC  Horizontal Sync (47 Ohm)
12      /VSYNC  Vertical Sync (47 Ohm)
13      GNDRTN  Digital Ground (for /XCLKEN) Don"t connect with pin 16-20.
14      /PIXELSW        Genlock overlay (47 Ohm)
15      /C1             Clock out (47 Ohm)
16      GND             Video Ground for RED Analog (useful to know because 
some TVs need specific grounds for specific colors when using SCART/PERITEL 
SECAM video signal)
17      GND             Video Ground for GREEN Analog
18      GND             Video Ground for BLUE Analog
19      GND             Video Ground for CHV SYNC
20      GND             Video Ground
21*     -12V            -12 Volts DC (10 mA max) (A500/A600/A1200)
21*     -5V             -5 Volts DC (10 mA max) (A1000/A2000/A3000/A4000)
22      +12V            +12 Volts DC (100 mA max)
23      +5V             +5 Volts DC (100 mA max)
