The Apple DVI to ADC adapter, first introduced in 2002 and
produced through 2006, allows a DVI-equipped computer to connecting
to an ADC monitor by merging video, USB, and power into a single cable.

The term DVI means "Digital Visual Interface" and is a video
interface for digital video signals from a computer to a monitor.

The term ADC means "Apple Display Connector" and is a proprietary
connector for video, USB, + power in 1 Apple display cable.

Why this adapter matters:
SOLD Only two units left, very clean, and working when tested. SOLD














Beyond basic connectivity, vintage Macs like the SE/30 can be part of a fully functional retro network -- even today. With the right hardware, you can share files, access legacy software repositories, and even browse lightweight websites.
One of the most versatile solutions is the Asante Ethernet card, especially the Rev A model designed specifically for the SE/30 with both BNC (10Base2) and AUI ports, allowing flexible connections to coaxial or twisted-pair networks. If you're restoring an SE/30, get an Asante SE/30 Ethernet card.

Stay tuned for more restoration tips and retro tech guides -- and feel free to email me if you have questions or want to share your own vintage networking setup!
