A600 Junior RGB to HDMI
The A600 Junior motherboard has some very useful improvements compared to the original Amiga 600 motherboard. One such improvement is a bunch of through-holes under where the RF modulator usually goes (and can indeed go, if you're that way inclined) that provide all the signals required by RGB to HDMI adaptor boards, and also 5V and GND for power: The RGB signal through-holes are designed to take 2mm-pitch header pins, while the 5V and GND through holes accept the slightly larger 2.54mm-pitch pins, as you can see, here (credit: idoregesz.hu): There is no universal standard for RGB to HDMI boards, so no adapter exists that you can just plug into the Junior's RGB pins. I bought a basic RGB to HDMI board that looks something like this: I then mapped out the flat flex connector pins on the Denise adapter board: Now all I needed to do was get a PCB made that maps the Junior's RGB and power pins to these FPC connector pins. I went on easyeda.com and knocked up a simple design. A ...
