I found a copy of Lisp-11. It runs on a PDP-11 simulator on the RT-11 operating system. It is written in PDP-11 assembly language and comes with source code. It looks like it was written at the University of Texas about 1975.

The problem is that there is no documentation. I tried a few things (+ 1 2), + (1 2), (print "hello"), and they were rejected. If anyone has pointers to documentation for this, I'd appreciate it and would enjoy playing around with a bit of Lisp history.
