PDP-8 Scanner for PDP-10

This document provides technical specifications and operational instructions for the SCN680 (also referred to as SCN689) program. The program runs on a PDP-8 to emulate a hardware line scanner, enabling the PDP-8 to interface with a PDP-10 via the DA10 interface.

Key sections include: - Requirements: Details the hardware configuration (PDP-8, 680 Data Communication System, DA10 interface) and core storage requirements. - Operation: Provides step-by-step instructions for loading the program from paper tape, initializing, and starting the scanner. - PDP-10 Programming: Explains how to set initial conditions, process interrupts, and transmit/receive characters within the PDP-10 monitor. - Assembling Instructions: Describes the process for assembling the SCN680 source code for specific 680 hardware clock configurations.
