Tandy Color Computer 3 CoCo 3 RGB2VGA DE-0 Nano FPGA RGB to VGA converter

This custom built adapter is based on this design on Github:

https://github.com/bkw777/rgb2vga?tab=readme-ov-file

I had the PCB built by PCB Way (I have four extra PCB only unpopulated boards that I will include as well) and had to source an Intel DE0-Nano FPGA board for the project as well as print a case.

DE0-Nano box also included although not pictured.

All said, this was a pricey project and I am selling it for much less than I had paid.

In short, connect the included RGB cable to the bottom of your CoCo 3 and connect the other side to this box. Apply USB power to the box and plug the VGA out into any VGA monitor. It has a switch to turn on composite artifact modes as well, and invert the colors (see screenshots of the game "Downland" to give you an idea).

The RGB2VGA can be flashed with a 640x480 firmware or an 800x600 firmware. Currently I have it configured to 800x600 but you can easily reflash it following the instructions on Github.

Any questions please ask. Thanks!
