The 7100/66 was the middle of the Power Mac line when Apple introducedit in March 1994. Built into the Quadra 650 case, the 7100 containsthree NuBus slots and a PDS. To save money, the 7100 uses RAM forvideo (up to 615 KB, depending on resolution and bit-depth) and aseparate PDS card with VRAM, making it very easy to work with twomonitors. For best performance, use the video card, not motherboardvideo.
The 7100 was upgraded to 80 MHz in January 1995.
See our NuBus Video Card Guidefor information on adding a video card.
Note that these so-called NuBus upgrades do not go into a NuBusslot; they derive their name from the fact that they work in NuBusPower Macs. The processor upgrades fit into the PDS (ProcessorDirect Slot) which is normally occupied by a video card on the7100. These cards may also include a pass through connector (whichmay be an extra cost option) allowing you to plug the PDS videocard into the upgrade card.
The floppy drive mounting sled used in the IIvi, IIvx, Centris650, Quadra 650, and Power Mac 7100 can also be used for a harddrive if you no longer need the floppy drive.
7100av. Includes video-in and video-out. Supports 19" and21" monitors. Has 2 MB VRAM. (AV card can be added to any 7100 witha free PDS slot.)
