RM03/TE16 and RM03/TU77 Based VAX-11/780 System Configuration

This document is a configuration guide for the Digital VAX-11/780 computer system, specifically detailing setups using RM03 disk drives and TE16/TU77 tape drives, effective April 1980.

It outlines the initial system configuration, which includes 512KB ECC MOS memory, an RM03 disk drive, a TE16 or TU77 magnetic tape unit, a console terminal (LA120 DECwriter III), and basic I/O components (UNIBUS and MASSBUS adapters, and an asynchronous multiplexer for 8 EIA lines).

The guide then provides comprehensive details on system expansion:

• Memory: Explains how to expand local memory within the CPU cabinet (up to 4MB total) and via an optional CPU Expansion Cabinet (H9602-HA/HB) for up to 8MB of local memory, or through Multiport (shared) Memory options (MA780) to reach a maximum of 12MB total.
• I/O Adapters: Describes adding more UNIBUS (DW780 UBA) and MASSBUS (MBA) adapters, along with supporting devices like additional disk (RM03, RP06) and tape (TEE16, TEU45, TU77) drives.
• Communication: Details the expansion of asynchronous communication lines using various DZ11 multiplexers and distribution panels.
• High-Performance Channel Interface (DR780): Covers its use for connecting custom devices or linking two VAX-11/780 systems.

The document also specifies the cabinet configurations (CPU, CPU Expansion, UNIBUS Options) required to house these components, noting available expansion slots, power supply provisions, and cabling considerations. Finally, it provides environmental operating recommendations for optimal system reliability.
