In the disc-based version of the game there is an audio excerpt from the Star Trek: The Original Series episode "The Ultimate Computer". The quote is:
The filename, "PAT.WAV", may be in reference to one of the programmers, Pat McCarthy.
"Seminars and lectures to rows of fools who couldn't begin to understand my systems. Colleagues. Colleagues laughing behind my back at the boy wonder and becoming famous building on my work. Building on my work."
The filename, "PAT.WAV", may be in reference to one of the programmers, Pat McCarthy.
