This is a non destructive way of fitting a HDMI output to the Amiga 500.
Adding the RGBtoHDMI adapter to the original Amiga 500, gives it the ability to deliver a perfect digital HDMI output. When the small board is fitted inside the Amiga on the Denise Chip, the problem arise how to get the HDMI cable out of the Amiga.
I've come up with the following solution:
This little housing, for a Female HDMI connector, clips right on the Amiga case. I tried to design it in the A520 TV modulator style, so it should not look to much out of place in the 80' computer design.
What you need:
Ribbon Cable length about 30cm.
HDMI Female often called A4
mini HDMI male called C1
Tactile Switch Panel PCB Mount Momentary TACT Switch Push
Now 3d print the housing.
Remove Support and fit the HDMI PCB.
Sodder the push-button to the wire and the PCB pins.
Place the push-button rod.
Fit the switch on the bracket
Mount the bracket over the small tab. Make sure the button rod is right on the push button.
Put in the ribbon cable
Now place it on top of the Amiga.
Place the pins in the first row of the vents.
Put the ribbon cable through the vents.
Clip it on the Amiga top cover.
Lastly fit the wires inside the Amiga.
Fit the dupont on the protruding-pins and the switch-pins on the Denise PCB.
Fit the mini HDMI on the ribbon cable and connect it to the Raspberry Pi.
