Adafruit visited the history of the LOGO "turtle graphics" language not long ago.
Now on Twitter, folks have found the source code for the LOGO program used on Apple II computers. Source on GitHub.
It turns out that the program was written on a DEC PDP-10 minicomputer running the Incompatible Timesharing System (ITS).
I'd take it that the code is in 6502 assembly and the program works the whole Apple II memory map for functionality. Did ITS have a 6502 cross-compiler or did the MIDAS program have separate target environments?
Very interesting programming archaeology – see the source code yourself along with the full PDP-10 ITS image still maintained today.

"...funded via American Express cash advances. Early Apple funding was dicey like that."
Actually early Apple funding was mainly a guy with wild red hair and a fu-manchu from Chemeketa Park (supposedly named Jim) who would show up at the Good Earth Cafe and Organic Food Store in Los Gatos whenever the Homegrown Computer Club would meet there. He would come in with grocery bags of cash, Fairchild op-amps and Panama red. He would hand these over to Woz and the party was on.
