Power Macintosh 5500
The main logic board in the Power Macintosh 5500 is a plug-in logic board that incorporates a PowerPC 603e microprocessor, a second-level (L2) cache expansion slot, one or two Peripheral Component Interconnect (PCI) card expansion slots, enhanced AV features (audio and video input and output), and a PCI-based communications slot (comm slot II).
PowerPC 603e microprocessor running at 175 MHz, 200 MHz, 225 MHz, and 250 MHz (later with 275MHz).
0 MB on the main logic board; expandable to 128 MB using 168-pin JEDEC-standard 5-volt buffered EDO (extended data out) DIMM (dual inline memory module) devices with 2K refresh rate. Two DIMM slots are provided for DRAM expansion.
