Yes, it’s required for the RGB2VGA.
The DE-0 Nano is an FPGA development board. This is what does the video
conversion to VGA. The RGB2VGA board itself is an ADC/DAC board for the Nano.
In addition to CoCo3 15KHz RGB, the RGB2VGA and Nano combination will also
convert Apple ][ composite to VGA (with artifacts), as well as several other RGB/RGBI
systems.
The RGB2VGA is a project created by Luis Antoniosi. He did an excellent job on
this converter. Some minor improvements have been made; the resistor values
on the DAC portion (Roger Taylor), and I cleaned up and rerouted the PCB layout
for this run. The overall design and FPGA code are all Luis (CoCoDemus).
Some info here…
