Centerplane Connector
Note - Information for the CPU/Memory+ board centerplane connector also applies to the I/O+ and Disk board centerplane connectors.
The CPU/Memory+ board centerplane connector is mounted on the rear of the board, opposite the side of the board with the LED display and extraction levers. See Figure G-2. The connector is comprised of modular sections, each with its own set of receptacle pins. See Figure G-3.

A three-bladed power section results in 12 pins on the board. There are six, 120-pin rows, labeled A through F, spread across the remaining five sections; each section has 24 pins of each 120-pin row.
CPU Module Connectors
There are two connectors for each CPU module, one with 144 pins and the other with288 pins. See Figure G-4 through Figure G-6.

Centerplane Connector
Information for the I/O+ boards centerplane is the same as for the CPU/Memory+ board centerplane. See "Centerplane Connector".
SBus Connectors
The SBus+ I/O board has three SBus connectors (SBus 0, 1, and 2). The Graphics+
I/O board has two (SBus 0 and 2). See Figure G-11, Figure G-12, and Figure G-13.
