Power Mac 8100

The 80 MHz Power Mac 8100 was the fastest Power Mac when Apple introduced the line in March 1994, and it was the only model to ship from the factory with a 256 KB level 2 cache installed.

Power Mac 8100Built into a Quadra 800 case, the 8100 (a.k.a. 8115 in Japan as well as Apple Workgroup Server 8150) contains three NuBus slots and a PDS (processor direct slot). Like the other first-generation Power Macs, the 8100 uses system memory for video (up to 615 KB, depending on resolution and bit-depth). It also has a separate PDS video card with its own memory, making it very easy to work with two monitors. For best performance, use the video card, not motherboard video, when using just one display.

The 8100 was upgraded to 100 MHz January 1995, and a 110 MHz version was added in January 1995. It was replaced by the 8500 in August 1995.

See our NuBus Video Card Guide for information on adding a video card.

Note that these so-called NuBus CPU upgrades do not go into a NuBus slot; they derive their name from the fact that they work in NuBus Power Macs. The processor upgrades fit into the PDS (Processor Direct Slot) which is normally occupied by a video card on the 8100. These cards may also include a pass through connector (which may be an extra cost option) allowing you to plug the PDS video card into the upgrade card.

Variants

8100av. Includes video-in and video-out. Supports 19″ and 21″ monitors. Has 2 MB VRAM. (AV card can be added to any 8100 with a free PDS slot.)

Caution

  • You cannot upgrade from Mac OS 9.0 to 9.1 using updaters on NuBus models. You must use a full installation CD for OS 9.1.
  • Never run a 7100, 8100, 8150, or 9150 without a PDS video card or a PDS terminator. This can damage the motherboard. If the video card goes bad, you can replace it with another video card or use motherboard video after installing a PDS accelerator or “Apple Terminator, PDS, WGS 81XX.” Workgroup Server 8150 and 9150: PDS Needs Terminator, feedback from Mac Managers list, and personal experience.
