This document contains a series of electronic schematic diagrams for the RL11 controller. The sheets detail the various functional modules of the device, including:
- Unibus transceivers and register addressing logic.
- NPR (Non-Processor Request) control sequences.
- Data count register and DMA addressing.
- Silo operation for data buffering (parallel-to-serial conversion).
- Control logic for CSR and error registers.
- Micro-sequencer function control.
- Sector format control logic.
- Function termination and bus command handling.
- Phase-locked loop and data separation logic for disk reads.
- Write encoding and MFM compensation circuitry.
