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) . . .

5 Return 10 Sync return 15 Data clock (SCL)* . . .

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.
(From Sam Goldwasser)
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).
(From Brian Smither)
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.
(From Brian Smither)
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.

Personally, I think SCART connectors are dreadful things. I mean, who really wants a 20 pin monster when only about 3 or 4 are ever used in any application. But it seems they are being forced upon us!
I think most VCRs just use the composite video (in+out) and the two sound channels (in+out sterio). By the way, quite a common fault with VCRs is that the scart socket gets disconnected from the PCB inside the machine. I have fixed 2 VCRs with this problem. It is not surprising really, because the leverage on the huge plug must be quite large if you pull it out carelessly etc.
The quicher SCART dies, the better, IMHO.

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.
