Applications
NuBus was the proprietary expansion bus Apple introduced with the Macintosh II in 1987, and it remained the standard for high-end Mac expansion through the early 1990s. Cards like the 820-0185-08 were used in systems such as the Macintosh II, IIx, IIcx, IIci, IIfx, and Quadra 700/900/950 to drive high-resolution external displays — including Apple's own 13-inch and larger monitors of the era. Apple produced several NuBus video cards during this period to support different display configurations and resolutions as the professional Mac market demanded more screen real estate for desktop publishing, graphic design, and scientific applications. Today these cards are sought by vintage Mac enthusiasts and collectors restoring Macintosh II-era systems to working condition, as NuBus video cards are increasingly difficult to source.
This Apple 820-0185-08 Mac High Resolution NuBus Video Card has been tested and is in good working condition. The PCB is clean and free of visible damage. The DB-15 video output connector and NuBus edge connector both appear in good shape with no bent pins or corrosion noted in the photos. There is light handling wear consistent with a card that was previously installed in a system. Please review our photos and contact us with any questions before purchasing.
