SPEA Graphiti Painter 3
        I have a 2D graphics card from the early 90s typically used for CAD work, manufactured by a now defunct German company named SPEA. The card is the "Graphiti Painter 3". Instead of the regular HD15 VGA connector it uses a DE9 connector.
        
        To be able to connect it to a regular VGA monitor, I made an adapter using the following connection table:
      
|-------------|-----|-----|
|             | VGA | DE9 |
| Signal      | Pin | Pin |
|-------------|-----|-----|
| Red Video   | 1   | 1   |
| Green Video | 2   | 2   |
| Blue Video  | 3   | 3   |
| Ground      | 5   | 9   |
| HSync       | 13  | 4   |
| VSync       | 14  | 5   |
|-------------|-----|-----|
          
        
        
        I happened to have both connectors available on those cables typically connected to motherboards or SBCs. These can easily be linked together using male pin-header wires. In addition I added a ferrite core which may help with noise:
      
 
      
        
        The only drivers available for the card is for Windows 3.x or certain CAD programs, but here are some graphics generated by the "GDCLOGO.EXE" program run from DOS:
