VT50

This document, the VT50 Field Maintenance Print Set, provides comprehensive technical documentation for the assembly, maintenance, and repair of the VT50 terminal. It includes a detailed table of contents listing various units and assemblies such as the VT50 Unit Assembly, Monitor Power Supply, Data Paths Memory and Decoders, ROM UART and Timing unit, CRT Assembly, Keyboard A VT50, Transformer Assemblies, and various cable assemblies (EIA, extension, primary power).

The print set features exploded view diagrams, extensive parts lists detailing components and quantities for different VT50 variations (e.g., voltage/frequency, copier, cursor control models), and detailed schematics. Schematics are provided for the Monitor Power Supply, Data Paths Memory and Decoders (including logic gates, flip-flops, RAM), and the ROM UART and Timing unit (detailing cycle timing, instruction decoding, and control signals). Wiring diagrams and keycap layouts are also included for the Keyboard models, along with specific jumper settings for different VT50 features. The document serves as a complete technical guide for technicians working on the VT50 terminal and its various configurations.
