Physical Device Names

This document, Appendix C, provides a reference for physical device names in the system. It outlines: - Device Mnemonics: Conventions for three-letter mnemonics, including handling multiple controllers using third-letter suffixes (e.g., DTA/DTB). - RP11 Controller Addresses: Specific external page address ranges for DP and DPB devices and the corresponding behavior of the .STAT EMT. - Unit Identification: Instructions for using octal numbers to identify specific units in multicontrol scenarios. - Radix-50 Calculation: The mathematical formula used to derive Radix-50 equivalence for device identifiers, along with a table of character values.
