RGBtoHDMI adapter housing for Amiga 500

prusaprinters

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: <ol><li>mini HDMI male pcb +  HDMI Female pcb + ribbon cable.
