B) Macintosh II 4 Bit Video Card, Macintosh II 8 Bit Video Card - The Mac II High Res 4-bit and 8-bit video cards are compatible but will not drive Apple's 16-inch and 21-inch color monitors. Also, because these cards were designed only to drive the 12-inch High Res monochrome and the 13-inch RGB monitors, they have no sense line capability. Therefore, if they are placed in any Macintosh computer with a NuBus slot that is also supporting built-in video or a later version NuBus card, the boot up screen will automatically default to the old Mac II High Res 4-bit or 8-bit video card.
C) Macintosh II Hi-Res Display Card (4-Bit), Macintosh II Extended Hi-Res Display Card (8-Bit) - These cards are compatible with the Quadra 840AV.
D) Macintosh II Two-Page Video Card, Macintosh II Portrait Display Card, Macintosh II Portrait Display Card, (DB15 connector) - Apple does not recommend that these cards be used in the Macintosh AV series. While they will not harm the computer, there are some timing differences with certain cards.
E) Macintosh Display Card 4*8, Macintosh Display Card 4*8, Rev. B, Macintosh Display Card 8*24, Macintosh Display Card 8*24, Rev. B - The Macintosh 4*8 and 8*24 cards are compatible with the Quadra 840AV. If you're planning to use the Apple 16-inch or 21-inch color monitor with either of these cards, Apple recommends the Rev. B ROM upgrade, available from an Apple authorized service provider.
F) Macintosh Display Card 8*24GC, Rev. A, Macintosh Display Card 8*24GC, Rev. B - The Rev A card is incompatible. The Rev B card is compatible, but not in the accelerated mode.
G) Macintosh Display Card 24AC - The card is a 7-inch NuBus card and therefore compatible with the Centris 660AV, Quadra 660AV and Quadra 840AV computers. The card can suffer significant performance problems (speed) when used in its accelerated mode.
