Td8e Dectape Copy

Summary

The TD8E DECtape Copy user's manual describes a software utility designed for the PDP-8/E or PDP-8/M computer systems. The program enables users to copy properly formatted DECtapes using TD8E control and dual TU56 tape drives.

Key features and instructions provided in the manual include:

• System Requirements: A minimum of 4K of read/write memory, a terminal, a TD8E control unit, and at least one dual TU56 tape drive. The program can support up to 32K of memory and four dual TU56 drives.
• Loading and Operation: The program can be loaded via the Binary Loader or the Self-starting Binary Loader. Once loaded, the program uses a terminal-based dialog to accept user input regarding source and destination units, block ranges for copying, and an optional verification step.
• Error Handling: The manual details various error messages (e.g., Illegal Response, Select Error, Tape Error, Verify Error) and the appropriate corrective actions, which often involve restarting the dialog or retrying the operation.
• Efficiency: The utility supports copying specific blocks from one position to another or copying an entire tape. It also includes a "shortened dialog" option for simplified full-tape copying.
