Connect ADC monitor to HDMI source

Very odd I missed seeing your thread (started back in 2021) until today! Wow!

So the interface shown in your opening post allows you to use ADC displays on modern computers via HDMI? Or does your adapter allow the vintage computer (like a G4 Cube) to connect to modern HDMI displays? Or both?

ADC is using DVI signals, and HDMI is compatible with these signals. If you have an ADC to DVI adapter and a DVI to HDMI cable, you can connect a vintage Mac to a modern display.

Here is an ADC to DVI adapter:

But the interface shown in the first post is for the reverse, to use an Apple ADC LCD monitor with a modern computer. (It won’t work with the ADC CRT: it uses VGA signals)

I love the compact Macs from the middle 80s, but my other love is the PowerMac Mirrored Drive Doors with Apple Cinema Displays.
These displays have ADC connectors used to connect to specific graphic cards with ADC connectors. The Apple (and other) solutions to connect these monitors to DVI connectors is to use an ADC-to-DVI adapter with the power supply and USB connectors.
But today we do not have DVI based graphic cards and these Apple ADC-to-DVI adapters are quiet expensive.
I thought if I would like to use my beloved ADC based Cinema Display monitors (I own 5 of them) then I have to build an HDMI to ADC adapter.
And here we go, today I can show you two variants, one is the boxed version - like any adapters, the other is the extension card shaped adapter. I use external power source (max 28V/5A).

I’ve tried to find the adc connectors but haven’t found them for sale anywhere.
