Linc Extended Memory, Real Time Clock, And Peripheral Instruction Set

This document serves as a technical reference guide for the mnemonic codes and functions of various LINC computer system components and peripherals. It provides a detailed table of instructions for:

• Extended Memory (MC12): Memory field management and instruction reading.
• Interrupt Control: Enabling and disabling interrupts.
• Real-Time Clock (KW12): Clock status, interrupt, and counter control.
• Mode Change and Power Control: Switching to LINC mode and power failure/restart instructions.
• Math (KE12): Multiplication, division, normalization, shifting, and AC/MQ register management.
• High-Speed Perforated Tape (PR1/1): Reader and punch control flags and buffer operations.

Additionally, the document includes a bit-assignment table for special registers (identifying specific tape and extended memory operations) and explains the logic for Index Class Addressing and Half-Word Class Addressing.
