DEC 3000 Model 800/800S/900 AXP

This document is an options guide for users of the DEC 3000 Model 800/800S/900 AXP system, providing detailed instructions for installing and removing internal hardware options. It is structured into chapters covering an options overview, preparation, specific installation/removal procedures for different components, and system restoration.

Key preparatory steps involve backing up files, safely shutting down system software and hardware, entering console mode to display and review current system configurations (drives, memory, TURBOchannel modules) using commands like show device, show memory, and show config. Users are instructed on how to properly remove system panels (cover, side panels, front panel) and to always use an antistatic wrist strap to prevent static discharge damage to internal components.

The guide provides step-by-step procedures for installing and removing:

• Removable-media drives (e.g., CD, tape, diskette drives), including SCSI ID setting and cable connections.
• Fixed disk drives, specifying preferred SCSI addresses for various positions.
• Memory modules, detailing module sizes, configurations, and installation/removal from Memory Mother Boards (MMBs).
• TURBOchannel option modules for graphics, multimedia, and communications, including slot selection and module seating.

Finally, the document covers restoring the system by replacing panels, properly storing the antistatic wrist strap, restarting the system, and verifying successful option installation by re-checking configuration displays and troubleshooting any errors that may appear. The guide stresses the importance of careful installation to prevent component damage and potential warranty issues.
