  • The PowerMac 8100 as said to be the fastest, most expandable first-generation PowerMac at that time surely so inviting to buyers. It was originally priced at $4,250. I guess it’s too expensive to have that unit knowing its specifications. GAR Labs

  • 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. car title loan
