The Commodore Amiga produces RGB video output @ 15khz. It has the ability to run in a higher resolution mode which causes a crazy amount of flicker when the screen refreshes. While I totally respect and give props to the Amiga friends over the years, their monitors seemed to always be a downfall. As a MS-DOS and VGA just didn’t have that issue.
This isn’t a new trick and has done before. But here is some slight documentation. I used one of the scalers that are popular with us arcade people to scale the video to drive a VGA monitor. This is pretty well known, really the most limiting part is getting hold of DB-23 connectors. In my case I used a DB9 as the input so I could re-use the DB-23 to DB-9 monitor cable with the scaler. I have a plastic project box on order from eBay/China to house the scaler and mount the connectors. I was more than impressed by the output from the scaler board, it looks really good.
Quick success and rapid turn around on this!
If you want to do the same using the DB9, I used a DB9 male solder type D-SUB.
Always check the pin labels on the plastic just to double check direction.
Pin 1 = Black, GND
Pin 3 = Red
Pin 4 = Green
Pin 5 = Blue
Pin 7 = Grey = Sync
The Yellow wire is not needed, no connection to the separate HS and VS pins on the scaler board.
