===1. Introduction.===
This document discusses building a monochrome vga cable for the Atari ST. It is relatively straightforward and no more complicated than connecting the right pins together.

===2. Atari ST 13-Pin DIN Pinouts.===
The following is viewed from the back of the connector, ie. solder connections;

* * * * 4 3 2 1

* * * * 8 7 6 5

* * * * 12 11 10 9

* 13

1 = Audio Output 2 = Composite Video
3 = General Purpose Output 4 = Monochrome Detect
5 = Audio In 6 = Green
7 = Red 8 = Plus 12-Volt Pullup
9 = Horizontal Sync 10 = Blue
11 = Monochrome 12 = Vertical Sync
13 = GND

===3. Standard VGA Pinouts.===
The following is viewed from the back of the female connector, ie. solder connections;

* * * * * 1 2 3 4 5

* * * * * 6 7 8 9 10

* * * * * 11 12 13 14 15

1 = RED 2 = GREEN
3 = BLUE 4 = ID2
5 = GND 6 = RED GND
7 = GREEN GND 8 = BLUE GND
9 = KEY/NC 10 = SYNC GND
11 = ID0 12 = ID1
13 = Horizontal Sync 14 = Vertical Sync
15 = ID3

===4. Level Adjusting Resistors.===
Resistors of 150ohms to be placed on the Red, Green, and Blue lines.

===5. Atari ST to VGA Connector Wiring Assignments.===
{| border="1"
!ST Signal Name || 13-Pin DIN || VGA || VGA Signal Name
|-
|Audio Output || 1
|-
|Monochrome Detect || 4 || 5 || GND
|-
|Horizontal Sync || 9 || 13 || Horizontal Sync
|-
|Monochrome || 11 || 1+3+5 || Red+Green+Blue
|-
|Vertical Sync || 12 || 12 || Vertical Sync
|-
|GND || 13 || 5 || GND
|}

===6. VGA Common Grounds.===
A number of the pins within the female VGA connector need to be shorted to GND. Pins 4,5,6,7,8,9,10, and 11. On the actual connector, these are as follows, viewing from behind;

* * * *----* 1 2 3 4 5
\
*----*----*----*----* 6 7 8 9 10
/
* * * * * 11 12 13 14 15
