Digital AlphaStation 400 Series Upgrade Information

This document serves as a comprehensive guide for customers and Digital Services on upgrading various legacy Digital systems by transferring compatible hardware options to a Digital AlphaStation 400 Series system. It provides detailed, step-by-step procedures for disassembling older systems like the DECpc AXP 150, various DEC 3000 models, VAXstation 4000 models, and DECstation 5000 models to remove internal or external components.

The guide outlines a general upgrade process that includes safely shutting down the system, disconnecting all cables, removing external covers and internal components (such as disk drives, removable media drives, option boards, and graphics modules), and correctly setting SCSI IDs for relocated drives to ensure unique addresses (with SCSI ID 0 typically reserved for factory-installed drives).

Supported upgradeable options include specific SCSI disk drives (e.g., RZ25L, RZ26L, RZ28), tape drives (TLZ06, TZK11), CD-ROM drives (RRD43), monitors, and expansion boxes. Critical safety warnings, such as using antistatic precautions to prevent component damage, are emphasized throughout the procedures. The document also provides instructions for completing the upgrade by installing options into the new system, updating service contracts, and returning any un-upgradeable systems or components to Digital. Notably, some older VAXstation models are explicitly stated to have no upgradeable options for the AlphaStation 400 Series.
