INTERLISP
From Computer History Wiki
INTERLISP is a LISP dialect developed at Xerox PARC from BBN LISP.
INTERLISP-10
The first version of INTERLISP was essentially a renaming of the latest iteration of BBN LISP, which was hosted on PDP-10 computers running TENEX. When build for running on a Maxc, it can use the compact Byte Lisp instruction set provided by that computer.
Interlisp-D
INTERLISP was ported to the Xerox D machines, and this version was called Interlisp-D.
