The RGBtoHDMI Video Interface Board converts the RGB video signal from vintage computers like the IBM PC (MDA/CGA/EGA) or Apple II to an HDMI signal compatible with most modern TVs/Monitors. The board connects to a Raspberry Pi Zero, 3B, or 4 (not included) running custom firmware and is able to correctly sample each of the supported video modes to give a pixel-perfect rendition. The HDMI output is locked to the input so there are no frame drops, repeats or tears and it also has low lag of around 4 milliseconds. An addon analog interface board is available which support a limited number of computers with a few levels of analog RGB / YUV or monochrome composite output.

In the dropdown list above, you will find additional boards that make it easier to use with systems like Amiga and Atari as well as accessories like a case, various cables, etc.

This product is produced in association with the developers of the RGBtoHDMI project. A portion of the proceeds will be shared with the product developers to help continue development of this wonderful device!

You can click on the drop down box above to select various add-on boards and accessories depending on your needs.

    Hi everyone,

    received a good sealed box with all the devices I ordered, and all of them perfectly soldered.
    Now just waiting for the Raspberry PI Zero and to finish the reconditioning of my Apple //e 😉

    Thanks Aaron.

    Hello Aaron.
    I received the RGBTOHDMI with analog device. Works well on my Dragon 32. It took one month to travel from your California to my meadow in France. It was worth waiting. And thank you for your videos.

      I am sorry it took so long. I hope we get back to normal soon!

    I received the RGBtoHDMI and the Raspberry Pi Zero within a couple of days of each other. I made two mistakes. I ordered the RGBtoHDMI without also ordering the IDC to DB9 cable. My bad. I happened to have an RS232 IDC to DB9 cable from a RS232 card that worked (I had to bend over a couple of pins on the RGBtoHDMI IDC header since it was 12 pin and my cable was 10 pin). It worked great. The other mistake I made, was that I ordered the Pi Zero without the IDC header already soldered on. I found one in my bag of goodies and soldered it on. Had I not made these two errors, it would have been a simple plug and play. Once I figured out that I needed to select the Hercules profile instead of the MDA profile, everything worked perfectly. I would highly recommend this solution if (should I when) your CRT display fails.
