Here is the source code to LLogo in MACLISP, which I stashed from the MIT-AI ITS system. It's a fascinating historical document, 12,480 lines of beautiful practical lisp code, defining where the rubber meets the road, with drivers for hardware like pots, plotters, robotic turtles, TV turtles, graphical displays, XGP laser printers, music devices, and lots of other interesting code and comments.

When I was 17, Terrapin published my first commercial code on their C64 Logo utilities disk: a Logo Adventure program, a simple non-graphical game that showed off Logo’s list processing and functional programming capabilities.

Lars Brinkhoff got some of this code to run in MacLisp on an emulator! (I don't know how much of the historical hardware the emulator supports yet, but he's probably worked on some of that too. ;) )
