Abstract

The Conversational Compiler System described herein is implemented on the Scientific Data Systems Model 940 Time-Sharing System. The SDS-940 has, as its Central Processor, a modified SDS-930, the modifications for which were developed at the University of California at Berkeley by Melvin Pirtle. This hardware includes a paging scheme, a set of privileged instructions for monitor as opposed to user mode of operation, and the ability to perform input/output operations to secondary memory while computing.
