MS670-BA/CA MOS Memory Option

This document, the "MS670-BA/CA MOS Memory Option Installation Guide," provides step-by-step instructions for authorized service personnel to install and verify MS670-BA (32 Mbytes) and MS670-CA (64 Mbytes) MOS memory modules. These modules are designed for systems utilizing the KA670 CPU within a BA440 enclosure, such as the VAX 4000, model 300 system pedestal.

The guide covers:

• Product Description: Details the features of the BA440 system enclosure and the specifications of the MS670 memory modules, including their capacity and connectivity.
• Installation Procedures: Provides instructions for pre-installation steps (customer software backup, system shutdown, unpacking, and inspection), checking system configuration, powering down the system, and the physical installation of the memory modules into the BA440 backplane. It emphasizes antistatic precautions and proper module seating.
• Testing and Verification: Outlines comprehensive procedures for testing the newly configured system using the KA670 CPU's ROM-based power-up self-tests and acceptance tests. It details various diagnostic commands to verify memory recognition, check for errors, and troubleshoot. Finally, it describes using the MicroVAX Diagnostic Monitor (MDM) for system verification and the process for rebooting the operating system after successful installation.
