This was on the cover of a book and it prints a maze using block characters? copilot said the block characters part but not the maze, i remembered that after seeing the "one of two block characters."

unfortunately that requires a BASIC to run, which will probably be larger than 256B and possibly even 1800000B - the mind is born .prg can just be "run" on the computer it was written for with no interpreter.

yes, I am aware of the Commodore 64 :) and I also know what machine code is.
