I think you're missing a definition of \blackbox. That's not a  
standard TeX command (it's certainly not built in, nor is it defined  
by Knuth in plain.tex). Hence, your log includes:

! Undefined control sequence.
\marker ...redlistdepth (impossible)\or \blackbox
                                                   \or --- \else * \fi

And if you continue past this error, nothing is printed for the  
undefined \blackbox.

Maybe TeX for the Impatient offered a definition of \blackbox  
earlier, and thereafter assumes it?
