RGBtoHDMI VS Amiga-Digital-Video

It's very DIY, and doesn't see much love from the Apple community, but RGBtoHDMI has a great support community. It seems that Raspberry Pi Zeros are back on the market again, too

RGBtoHDMI (reseller)

If you are already going the extra mile, you can convert directly from the TTL signals to HDMI with the RGB2HDMI adaptor.

https://github.com/hoglet67/RGBtoHDMI/wiki/Supported-Computers lists "Commodore 128-80col"

RGBToHDMI works on a lot more systems. https://github.com/hoglet67/RGBtoHDMI/wiki/Supported-Computers has the full list but it's pretty much all 8 and 16 bit computers.

My advice is to forget about trying to find a monitor that will accept the signals directly and just get an upscaler instead. Depending on the computers, you may be able to use an RGB2HDMI, or you could use an OSSC with a CGA2RGB to convert TTL RGB/monochrome to analog.

Just to expand your options a bit, you can also use a 15 kHz analog RGB monitor (Amiga monitor, PVM, modded consumer TV, etc.) with a CGA2RGB, or an HDMI monitor with an RGBtoHDMI.

There's rgb2hdmi, Amiga OCS/ECS specific, and OSSC, for any VGA/RGB/Component source.

I use a version of this for my 2000s (https://github.com/c0pperdragon/Amiga-Digital-Video) but on my 500s PiStorm and an external RGB SCART to HDMI box that you can buy cheap AF on eBay.

Computers: 1. Commodore 64 Pi1541 - emulates 1541 floppy drive for Commodore 64. Video review 2. Amiga RGB2HDMI - convert Amiga's RGB video signal into friendly HDMI output. Video review 3. Amiga Pistorm - emulates faster version of Motorola 68000 CPU. Theoretically, can be used in any machine that uses 68k chip. But I hear mostly about Amiga Pistorm implementation. Basically, Pi Zero emulates faster CPU, video modes, acts as HDD storage, HDMI output etc. Pistorm does what popular Amiga accelerator boards do for hundreds of space bucks. Video review

If you want to go the HDMI route, there is this device. It sits in one of the chip sockets and uses a PiZero to add a HDMI socket.

Would HDMI or DVI be acceptable? Maybe this would work for you there are a few people on eBay selling them, the hardest part is getting a raspberry pi

You can build the adapter board yourselfhttps://github.com/c0pperdragon/Amiga-Digital-Video

For me at least - for ease of use and display quality, I have found the OSSC very good and works well my my original Xbox with component cables, however I am looking to try out the Raspberry Pi option with my A500 at some stage, especially since it can be powered and mounted internally within the Amiga which seems pretty cool.
