Dan Murphy had an extensive archive of old sources for BBN LISP (and many.

In particular, Murphy implemented a software-based virtual memory and demand paging system within his LISP implementation, and Bobrow and Murphy studied its performance. In their PDP-1b implementation of LISP, Bobrow and Murphy grappled with issues of supporting a large LISP memory on a machine with a small physical memory. It was both the command language and the programming language, a la JOSS and such systems of that day.' one of the things we did was build a timesharing LISP system on the PDP-1 - that is, a multi-user system for which the primary (and only) interface language was LISP. 'Bobrow and Murphy started with the LISP 1.5 definition and looked at Deutsch's code for the PDP-1b, but their implementation had a completely new code base for what they called BBN-LISP. Rewritten at BB&N to become the conceptual predecessor of BBN-Lisp, which in my PDP-1 Lisp implementation, as you probably know, was extensively The first LISP at Bolt Beranek and Newman Inc.
