RK11C-RK03-Connectors

This document is a detailed signal mapping or pinout cross-reference table for disk drive interface signals, primarily for the DR Bus (Disk Drive Bus).

It provides a comprehensive list of signals, showing their:

• RK11 Signal Name: The primary descriptive name of the signal.
• BC11 Pn: The corresponding pin assignment on a BC11 connector or board.
• RK03 Input Pin: The specific pin designation on an RK03 device where the signal is input.
• Diablo Signal Name: The equivalent or corresponding signal name as used in a Diablo system.
• RK03 Output Pin: Mostly indicates "Same," implying the output signal name matches the input or RK11 signal name.

The signals covered include a wide range of disk drive operations and status, such as:

• Cylinder (Track) and Sector Addressing (various bit lines).
• Read/Write Operations (e.g., Data, Clock, Gates, Write Check, Write Protect).
• Unit Selection (for units 1 through 4).
• Control and Status Signals (e.g., Strobe, Index Mark, File Ready, Seek Incomplete, Restore, Ready to Seek/Read/Write, High Density Indication, Head Select).
• Interlock and Acknowledgment signals.
• Power (+5V for Terminator) and Ground connections.
• Designations for No Connection or Unlabeled/Unconnected pins.

The table serves as a technical reference to understand how these disk drive signals are named, routed, and translated between different hardware components like RK11, BC11, RK03, and Diablo systems.
