File:Power Macintosh 9600 logic board schematic (820-0865-A).pdf

Apple Computer's "SCHEM, PCB, MN LG BD, 9600" for PCB 820-0865-A: 28 PDF pages of 600 dpi black-and-white scans. Sheet 1 is the table of contents and revision notes; the first note describes the drawing as based on the production 9500 board with the power supply connectors J39 and J36 changed. Sheets cover the processor connector, Hammerhead memory controller, data multiplexers, ROM, L2 cache, DRAM DIMM connectors, the two Bandit PCI bridges and six PCI slots, Grand Central, Curio, serial drivers, SCSI and MESH, supply connectors, power control and Cuda (sheet 20), NVRAM, AWACS audio (sheet 22), pull-ups, clocks and test points, and on sheet 27 the board stack-up, net voltages and unused designators. Sheet 22 carries handwritten value changes to several small ceramic capacitors.

It covers the first 9600 logic board; the later board for the 300 and 350 MHz models is not this drawing.
