DEC 3000 Model 900 AXP Upgrade Information

This document, titled "DEC 3000 Model 900 AXP Upgrade Information" and published by Digital Equipment Corporation in July 1994, serves as a technical guide for users and Digital Services personnel.

Its primary purpose is to outline which hardware components and options from older systems—specifically the VAXstation 4000 Model 90/90A, DECstation 5000 Model 240/260, and DEC 3000 Model 500/500X AXP—can be successfully transferred and utilized, either internally or externally, with a DEC 3000 Model 900 AXP system.

The manual provides detailed, step-by-step instructions for:

• Identifying and removing various options, including fixed disk drives, removable-media drives, graphics modules, memory, expansion boxes, tape/disk drives, monitors, and input devices.
• Setting SCSI IDs on drives to ensure proper system communication, with specific guidance for different drive models.
• Installing new mounting brackets when transferring drives from VAXstation or DECstation systems (not required for drives from the DEC 3000 Model 500/500X AXP).
• General precautions, such as using antistatic measures to prevent hardware damage.
• Completing the upgrade by installing the transferred options into the new system.
• Returning legacy systems and non-upgradeable devices to Digital.

In essence, it's a practical guide for hardware migration and component reusability within Digital's workstation and server product lines from the mid-1990s.
