Lap6-Dial-Ms for the Rk8f

This document serves as a technical supplement to the LAP6-DIAL Programmer's Reference Manual, detailing new features and operational procedures for using the DIAL-MS system with RK8F disk drives.

Key features and updates include:

• Support for Multiple Disks: The system now supports the use of up to four RK05 disk drives, providing increased random access storage capacity for PDP-12 users.
• Increased Logical Unit Size: The logical unit size has been expanded from 1000 to 1600 blocks to facilitate full disk access.
• Operational Limitations: Certain DIAL commands (AP, SP, AB, SB, LO, AS, LI, QL, and PS) do not support files extending beyond block 777; users must utilize the PIP utility to manage files in that storage area.
• System Procedures: The document provides step-by-step instructions for initializing a formatted disk and the specific switch settings and bootstrap procedures required to restart the DIAL-MS system from the disk.
