The BBN-LISP system: Reference Manual

This document describes the BBN-LISP system currently implemented on the SDS 940. It is a dialect of LISP 1.5 and the differences between IBM 7090 version and this system are described in Appendix 1 and 2. Principally, this system has been expanded from the LISP 1.5 on the 7090 in a number of different ways. BBN-LISP is designed to utilize a drum for storage and to provide the user a large virtual memory, with a relatively small penalty in speed (using special paging techniques described in Bobrow and Murphy 1967).
