The8100/80 was the fastest Power Mac when Apple introduced the line inMarch 1994, and the only model to ship from the factory with a 256KB level 2 cache installed.
Built into the Quadra 800 case,the 8100 contains three NuBus slots and a PDS. Like the otherfirst-generation Power Macs, the 8100 uses RAM for video (up to 615KB, depending on resolution and bit-depth). It also has a separatePDS card with VRAM, making it very easy to work with two monitors.For best performance, use the video card, not motherboardvideo.
The 8100 was upgraded to 100 MHz January 1995, and a 110 MHzversion was added in January 1995. It was replaced by the 8500 in August 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 the8100. 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.
8100av. Includes video-in and video-out. Supports 19" and21" monitors. Has 2 MB VRAM. (AV card can be added to any 8100with a free PDS slot.)
