DECstation 3100 Desktop Workstation

This document contains the functional specifications for the KN01 system module, which serves as the core of the DECstation 3100 and 2100 desktop workstations. It details the system architecture, including the R2000 processor, parity-protected memory, ROM, and various subsystems such as the serial interface (based on the DC7085 gate array), SCSI interface (based on the DC7061 SII gate array), and network interface (utilizing the LANCE chip). The document also covers address mapping, interrupt levels, power requirements, and low-level hardware interfaces including video, battery-backed-up RAM, and programmable cursor control.
