The creator of the “Origin” 17-port HDMI switch that was previously reported in June has put a few prototype units up for sale:
https://www.ebay.com/itm/253821357624 – HDMI v1.3b version / used more expensive switches
https://www.ebay.com/itm/253907737462 – HDMI v1.4 version / slight compatibility issues (described on sale page)
These switches are sold as-is and made of four 5-port HDMI switches linked together and hasn’t been tested in all retro-gaming environments, so proceed at your own risk. If any consoles have issues, I suggest trying a different input, to make sure you have one closest to the output port.
It’s my opinion that a touch-screen HDMI switch like this is absolutely amazing and something I’d badly want myself. Maybe the creator would consider open-sourcing the project and work with someone on taking the amazing-looking LCD touch screen and integrating it with a custom 10×2 matrix switch? Maybe even with a DisplayPort switch that’s HDMI compatible…
