VAX 4000 Model 200 Technical Information

This document, "VAX 4000 Model 200 Technical Information," provides a comprehensive summary of the VAX 4000 Model 200 system, including its base configuration, optional components, and system expansion guidelines.

The document details the base system, which features the KA660-AA/BA CPU module and MS650-Bx memory modules, housed in either BA430 or BA215 Q-bus enclosures. It outlines the system's firmware (console program, self-tests, and primary bootstrap) and power-up procedures. A significant section describes the Console I/O Mode, including control characters and various commands for system control, monitoring, and diagnostics. The integrated Digital Storage Systems Interconnect (DSSI) architecture is explained, highlighting its bandwidth, node support (including Integrated Storage Elements - ISEs), and performance benefits. Detailed specifications for the CPU, memory, Ethernet, and DSSI connector are provided.

The document then extensively lists specifications for a wide array of optional components, categorized into:

• Mass Storage: Various disk drives (RA-series, RF-series ISEs), CD/optical disc subsystems, and tape drives (TF85, TK50, TK70, TLZ04, TSZ07, TSV05, TU81-Plus) along with their respective controllers.
• Communications: Asynchronous multiplexers, Ethernet and Token Ring controllers, asynchronous controllers with integral modems, synchronous controllers, and the DECserver 200.
• Real-Time Options: Digital-to-analog and analog-to-digital converters, various controllers, parallel interfaces, and programmable real-time clocks.
• Printer Interface: The LPV11-SA.
• Graphics Adapters: The VS30U.

Finally, it offers guidelines for system expansion, including compatible expander chassis options (e.g., BA213F, B400X) and provides configuration worksheets and power requirements for planning additional components.
