DTBOOT Specifications

This document describes DTBOOT, a bootstrap program designed for the DECsystem-10 computer family. DTBOOT facilitates the transfer of programs between core storage and DECtape files, along with various utility functions.

Key Features

• Load and execute programs from DECtape (monitors, diagnostics, etc.).
• Perform directory operations: list, delete files, and initialize tapes.
• Support for core image manipulation, including dumping core to tape.
• Compatible with the DECsystem-10 monitor.

Operational Overview

DTBOOT requires a DECsystem-10 processor, console typewriter, and at least one DECtape transport. It is loaded into memory from paper tape via the READIN switch. Operators control the program using simple command strings (e.g., DTA3:TOPS10.SAV/L) and various switches to clear core, set starting addresses, or merge files.

Comparison with TENDMP

DTBOOT is intended to supersede the older TENDMP program, offering advantages such as: - Better support for long .SAV files. - More standard command syntax and helpful defaults. - Improved tape-identifier management. - Better DECtape control handling.
