MSV11-D, -E User's Manual

This document is the user's manual for Digital Equipment Corporation's (DEC) MSV11-D and MSV11-E LSI-11 memory options. It provides comprehensive information for installing, configuring, and maintaining these memory modules in LSI-11 microcomputer systems.

Key aspects covered include:

• Introduction and General Description: Details the various MSV11-D (16-bit, no parity) and MSV11-E (18-bit, with parity) models, their memory capacities (4K to 32K words), and their LSI-11 bus compatibility as "doubleheight" modules. It highlights features like on-board memory refresh, volatile memory with battery backup option, and dynamic MOS technology.
• Specifications: Outlines electrical requirements (power consumption), environmental operating and storage conditions, and physical dimensions.
• Installation: Guides the user through configuring module switches and jumpers for specific applications, such as selecting the starting memory address (from 0 to 128K, with notes on LSI-11 system limits), implementing battery backup power, and enabling/disabling a portion of Bank 7. It also includes instructions for physical installation into the system backplane.
• Technical Description: Explains the internal workings, including the memory array organization, addressing logic, timing and control logic for various bus cycles (DATI, DATO, DATIO), the on-board memory refresh process, the charge pump circuit that generates the necessary -5V, and the dedicated parity logic functions present in MSV11-E models.
• Maintenance: Lists available memory diagnostic programs for testing the modules and provides information on DEC's maintenance services.

In essence, it's a complete guide for users to understand, set up, and troubleshoot their MSV11-D and MSV11-E memory modules.
