Yeah you're buying not only an apple preheprial but a defacto limited edition, vintage one. No ones gonna charge you less for that once they figure out how to market it.
I had one of these. I sold it 10 years ago for about double what they cost new when I bought it. For a period of time they couldn’t give these things away and I’m fairly certain I bought mine open box at MicroCenter.
A big problem with this is that if someone is goodwilled and sells their own adapter on eBay for cheap. Someone else would buy it to sell it at the 250,- price for profit.
What's that, the company infamous for being restrictive as hell in regards to usability, interoperability, repair, and even infamously went to court to defend their right to throttle their consumer's hardware capabilities to force them to upgrade isn't supporting their legacy hardware?
Apple never sold this dongle. Belkin did. The video card typically has two connectors and this allows you to use a second standard monitor, which was not common at the time.
Fyi, this case is a bit different than other Apple issues. For one thing, the ADC port the adapter is for apparently only showed up on the G4/G5 Power Mac and G4 Cube. Secondly, the ADC connector is, on paper, superior to DVI as it can not only carry video (both digital and analog, which normally require different DVI ports), but also audio, USB and power. In reality it didn't work so well because the couldn't carry enough power to run a CRT or even the higher-ens cinema displays. This lead to Apple realizing they screwed up and discontinued it in support of an unbundled cable.
You do know that one of them is an operating system basically a bunch of zeros and ones and the other one is a company? Just to shit on linux you put it into a totally unrelated sentence.
