They are palette variants of machines already in the list, so interleaved
they read as duplicates. The console's own name decides it - eleven of
the thirty-eight are called Black or Blacker something - so they sort
last within a hull tab as well as overall.
Blacker Broccoli's console picture is a Bug, but the game draws it on the
Mule hull like every other Broccoli: the console entry is simply wrong,
and saying so on the card raised a question the card could not answer.
Blacker Tarantula keeps its note, where the console and the game really
do disagree about the hull.
