MicroVAX II Upgrade Installation Guide

This document is the MicroVAX II Upgrade Installation Guide, published in 1985 by Digital Equipment Corporation.

It provides detailed, step-by-step instructions for converting existing MicroVAX I or BA23 enclosure-based MICRO/PDP-11 systems to a MicroVAX II system.

The guide covers:

• Identifying and unpacking the components of the MicroVAX II upgrade kit, including the MicroVAX II CPU Module (M7606-A), RQDX disk controllers, memory modules, and accessories.
• Preparing the system by removing the cover, unplugging power, and labeling cables.
• Replacing the CPU distribution panel insert.
• Carefully removing specific old modules (identifying them by part number and slot).
• Installing the new MicroVAX II CPU, memory modules, and disk controller, with crucial warnings about anti-static precautions and specific slot placements to avoid damage (e.g., M7606/M7607/M7608 modules should not be installed in slots 4-8).
• Reassembling and reconnecting the system, including power and console cables.
• Replacing the system medallion with the new MicroVAX II medallion.
• Instructions for returning the old CPU modules (MicroVAX I or MICRO/PDP-11) to Digital Equipment Corporation using the upgrade kit's packing material.

The document also includes an appendix listing various module part numbers and their functions.
