PDP-11 Computer Monitoring System.

Abstract

This report describes a hardware system for controlling and accounting for use of up to 15 PDP-11's with up to 700 users. The system functions much like a software accounting system on a large time-sharing system and is designed for compatibility with DEC system-10 accounting packages. The hardware includes an SBC-80/10 microcomputer interface located in each PDP-11. The interface requires one system unit in the PDP-11 box. The interface becomes 'bus master' when the PDP-11 is turned on. It remains 'bus master' until the PDP-11 user has correctly 'logged on' to the system through the console terminal. The accounting data and user identification are stored on a PDP-11/04 system which communicates with each SBC-80/10 microcomputer via a serial RS232 communications link. The user identification is generated in a DEC system-10 and transferred to the PDP-11/04 over a serial asynchronous communication link. Account data is periodically transferred to the DEC system-10 via the same communications path. (Author)
