Many thanks to Hackaday’s recent article for bringing this to my attention:
Amiga Now Includes HDMI By Way of a Raspberry Pi Daughterboard
Back in June 2020, Bob reported on the RGBtoHDMI project that initially aimed to extract the 3-bit (8 colours) RGB output of the BBC Micro computer and convert it into pixel-perfect digital video via custom firmware running on a Raspberry Pi:
Since then, the project has been extended to support 6-bit (64 colours), and 12-bit (4096 colours). In addition, a new open source daughter board has been created by GitHub user c0pperdragon that allows easy, direct-plug access to the Amiga 500’s Denise chip.
Details on the original RGBtoHDMI project are on the project’s GitHub Wiki:

And likewise details of the Amiga 500 specific board and tools on its own GitHub page:

Great to see this project extending past its original design to include more hardware!
