“Dongle experts I spoke to told me that the world’s dwindling vintage dongle supply is a real, actual problem that threatens to make vintage computing much more difficult moving forward”.
I had no idea there was such a thing as a dongle expert. :)
That project is even a bit more involved because it looks to power an Apple display from a generic dvi video card. Going from DVI to ADC should be even simpler than the project you mentioned!
This puts me in mind of trying to find one of those dual FireWire/USB > 30 pin cables that Apple sold around the time of the 4th gen iPod. My 4g desperately needs one if I want to sync more than a few hundred tracks, because USB won’t charge it, and I haven’t owned a Mac with a FireWire port since 2011. But man, this things are pricey now, because they just aren’t available anywhere.
I could use a thunderbolt socket, but I’d need a TB3>TB2 adapter first, and Apple want £40 just for that. Then add on a TB2>FW adapter and suddenly I’ve spent twice what I paid for the iPod and the flashmod it’s running…
