Home / Commodore Amiga Hardware / Amiga RGB2HDMI Amiga RGB2HDMI€19,90 (excl. VAT) Add pixel-perfect HDMI output to the Amiga machines. For all Amiga versions that have a socketed DIP Denise chip and the required physical space inside, a rather small adapter board can be used to extract the digital video signal (12 bit) to a 40-pin connector compatible with the Raspberry Pi Zero. This can then be used with the RGBtoHDMI software to produce a perfect HDMI picture with very low latency (a few milliseconds at most). Will be needed but not included: Raspberry Pi Zero (any variant) Micro SD card (any) and some means to transfer data to it. Mini-HDMI adapter or adapter cable (may already come in a set with the Pi) Some HDMI extension to reach the outside of the computer case Out of stock Get an alert when the product is in stock: Get an alert Description Description Software The Raspberry Pi needs to have a version of the RGBtoHDMI software on its SDCard. A compatible release of the software is available from the RGBtoHDMI repository https://github.com/hoglet67/RGBtoHDMI/releases. Unzip the content of the archive to the root folder of a micro SD card, formatted as FAT32. This card goes into the Rasperry Pi Zero and contains all software needed. Because the adapter board contains a configuration selector, the Amiga profile is already preselected and can be used directly. Installation – no soldering required When you are not comfortable with a soldering iron or just don’t have one, you can easily obtain a Rasperry Pi Zero with preinstalled pin headers from various vendors. When you use this and don’t require the optional menu button (for expert use only), the whole installation is just done by plugging parts together. Depending on how you want to bring the HDMI signal out of the computer case, you may have to cut a hole in the case. Or to keep the case original, you could also bring the cable out through some other opening (like the expansion port), or just do not close the case at all. Step by step installation instructions There is also a nice Youtube video series from a user showing the installation process in more detail:https://www.youtube.com/user/brostenen Compatibility The first revision of the adapter board works with PAL and NTSC Amigas that have an OCS Denise (8362 variants).The current version of the board (V2) also supports a DIP-48 8373 SuperDenise (sorry, Amiga 600 users), but only as long as one of the OCS screen modes is used (320×256, 320×512 interlaced, 640×256, 640×512 interlaced). For very early models of the A500 and A2000 as well as all the A1000 models, some additional soldering to the main board is needed to bring the necessary signals to the Denise socket. Refer to https://github.com/c0pperdragon/Amiga-Digital-Video/issues/28 for more details on how this can be done. Please note that the HDMI signal will not carry any audio. You still need to get the audio signal from the RCA jacks as usual. If you absolutely have to merge the audio signal into HDMI there are dedicated external solutions for that. The output device needs to support at least 1024 lines because the mod quadruples the screen resolution. So I very much guess an early 720p TV will not work at all. Digital computer monitors normally already have a sufficiently high resolution. Also some monitors may refuse to work with a video signal with 50 frames per second as produced by the PAL Amiga variants. In such a case you can force the upscaler to 60 frames per second mode by pressing the menu button during power-up. If you have not installed the button, you can as well just semi-permanently put a jumper link on the button contacts instead. When you force 60 frames in such a way, you will experience screen-tearing or jumpy scrolling in games or demos, so this fall-back should only be used if it would not work at all otherwise.
