RLV12 Disk Controller

This user's guide details the RLV12 disk controller, which interfaces RL01 and RL02 disk drives to LSI-11 bus systems. It covers:

• System Specifications: Technical details including power requirements, addressing modes (16, 18, and 22-bit), and physical environmental constraints.
• Functional Description: In-depth explanation of the controller's architecture, including registers (CSR, BAR, DAR, MPR, BAE), FIFO memory, bus protocol, and the data separator read circuit.
• Configuration and Installation: Step-by-step procedures for setting device addresses, interrupt vectors, and memory parity error abort features using jumpers.
• Register Operations: Comprehensive breakdowns of control and status bits for all programmable registers.
• Command Set: Definitions of operations, including Read, Write, Write Check, Seek, and Maintenance functions, along with error recovery strategies.
• Disk Drive Operation: Overview of controls, indicators, and voltage/range settings for the RL01/RL02 disk drives.
