Chapter 3) PC Graphics



  3.1) VGA/SVGA



    3.1.1) Original VGA (31.5 KHz - 640x480)
(From Sam Goldwasser) 
SVGA (35-37 KHz - 800x600) 15 pin sub D: 

			  				         6
 1 Red (Analog)   6 Red   Return    11 (ID0) GND (Color)     11. . . 1
 2 Green (Analog) 7 Green Return    12 (ID1) NC (Color)        . . .
 3 Blue (Analog)  8 Blue  Retuen    13 Horzontal Sync          . . .
 4 Reserved       9 No Connect      14 Vertical  Sync          . . .
 5 Ground        10 Ground          15 No Connect              . . .
                                                             15  10  5
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.

    3.1.3) VGA (VESA standard)
(From Bob Myers) 
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).

15      -       N/C

Monitor ID bit 0: reserved
Monitor ID bit 1: GND = mono, OPEN = color
Monochrome monitors use the green signal



    3.1.5) Somewhat standard 9 pin VGA
(From Sam Goldwasser) 
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). 



  3.2) EGA



    3.2.1) Standard EGA
(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. 



    3.2.2) DB9 to DB15 cable
(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. 



    3.2.3) EGA - TTL
(From Sam Goldwasser) 
(15.74-21.85 KHz) DB-9 pin: 

 1 GND                    6 Secondary Green Video/Intensity
 2 Secondary RED Video    7 Secondary Blue Video
 3 Primary RED Video      8 H Sync TTL Positive
 4 Primary GREEN Video    9 V Sync TTL Negative
 5 Primary BLUE Video
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). 



  3.3) CGA - TTL
(15.75 KHz - 320x200 or 640x200) DB-9 pin: 

 1 GND                    6 Intensity
 2 Unused	          7 Unused
 3 RED Video              8 H Sync TTL Positive
 4 GREEN Video            9 V Sync TTL Positive
 5 BLUE Video



  3.4) IBM PCJr CGA 18-pin connector
(From Dale Larson) 
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



  3.5) Monochrome - TTL
(18.43 KHz - 720x350) DB-9 pin: 

 1 GND                    6 Intensity
 2 Unused	          7 Video
 3 Unused                 8 H Sync TTL Positive
 4 Unused                 9 V Sync TTL Negative
 5 Unused

  6.1) What is the pin out for ...?
(From Ralph Valentino) 
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.
