Note:
Monitor ID Lines ID1,ID0=NC,G for color; G,NC for Mono. ID0 only may be used.
Mono VGA is similar using only the Green Video and Return.

Note that many of the pins shown above as "no connects" (actually, these were sometimes used as monitor ID bits by many manufacturers) are now defined under the VESA Display Data Channel standard. This standard provides two protocols for display ID and control, including support for the full ACCESS.bus interface. The current definition of the "VGA" pinout per the DDC standard is:
6
1 Red (Analog) 6 Red Return 11 Monitor ID0 (opt.) 11. . . 1
2 Green (Analog) 7 Green Return 12 Data (SDA) . . .
3 Blue (Analog) 8 Blue Return 13 Horzontal Sync . . .
4 Reserved 9 +5 VDC (frm host)* 14 Vertical Sync . . .
5 Return 10 Sync return 15 Data clock (SCL)* . . .
15 10 5
Those signals marked with an asterisk would be supplied by the host only if the host supports the DDC2 protocol (I2C or ACCESS.bus).

For analog VGA/SVGA measured based on my VGA to 9 pin adapter. This is pretty standard as the NEC Multisync II and others use the same pinout:
Pin 1: Red Video Pin 2: Green Video Pin 3: Blue Video Pin 4: H Sync Pin 5: V Sync Pin 6: Red Return Pin 7: Green Return Pin 8: Blue Return Pin 9: Ground
NOTE: IBM PGC assigns pin 4 to Composite Sync and pin 5 is a no-connect.
BTW, don't use an EGA 9 pin extension cable to connect it to VGA. While this will work, the wires are not shielded or the wrong wires and you will get ghosting and ringing at vertical edges. I constructed mine using proper 75 ohm coax for the RGB and H and V sync as well (though it is not needed for the sync).

According to the CPD-1303 user guide:
Pin: 1 2 3 4 5 6 7 8 9 Analog GND GND RED GRN BLU GND --- H/HV V * DIG/NORM GND GND RED GRN BLU GND --- H/HV V /D1 GND GND RED GRN BLU INT --- H/HV V /D2/CGA GND GND RED GRN BLU INT --- H/HV V /D2/MDA GND GND --- --- --- INT GRN H/HV V /D2/EGA GND r R G B g b H/HV V r-g-b is secondary colors for 64 color EGA
* Sync on green automatic if H or HV is not assigned to pin #8.
SYNC: any polarity.
Vertical size depends on vertical frequency and can be adjusted manually.

A 9-pin (monitor) to 15-pin (video card) cable can be built as follows:
9-pin F 15-pin M
------- --------
1,2,6 --------- 5
3 --------- 1
4 --------- 2
5 --------- 3
8 --------- 13
9 --------- 14
This adapter will NOT permit you to run a standard VGA monitor from a MGA/CGA/EGA video card as the signal levels and scan rates are not compatible. It only applies to the CPD1303 and similar monitors.

BTW, don't use an EGA 9 pin extension cable to connect it to VGA. While this will work, the wires are not shielded or the wrong wires and you will get ghosting and ringing at vertical edges.

The above pins are looking at the COMPUTER connector so 1 to 9 would be right to left on the plug from the monitor.
It looks like the top row of the 18 are "A", bottom "B" and looking from the back, numbered 1-9 left-right they are labled as follow:
a09 = audio a05 = red a04 = blue a07 = green a06 = inten a08 = not(line over)comp sync drive a03 = not tv hor drive b03 = hor out drive a01 = not tv vert drive b01 = vert out drive a02,b02,b04,b05,b06,b07,bo8,b09 = all grounds

This is a list of the pinouts to the more common PC hardware interfaces. It is by no means complete. While I have taken care not to make any mistakes, I urge you to take caution when using these tables. Also, please keep in mind that these are only tables, they are not a guide to hardware hacking and do not attempt to explain drive capabilities, signal timings, handling care, or other interface issues. As always, make sure you know what you're doing before you start hooking wires to your PC.
