Some of my old workstations (Sun3, Apollo DN3x00/4x00) use ECL signals for their monochrome monitor. Since these monitors are already dead or dying I was looking for a conversion to something more modern. As I couldn't find anything I found the ULX3S boards, which already have everything for driving a HDMI monitor. So goal of this project is to use the FPGA board for converting the video signal.

Steps:

1. Bring up FPGA
2. Show something on the HDMI monitor
3. Use an input pin for receiving bitstream to show on monitor
4. Add H-Sync/V-Sync support
5. Build level converter board from ECL (video)/TTL (syncs) to 3.3V and connect to FPGA board
