TOUCAN'S TRIVIA: There are actually 9
levels of play in the TI-99/4A version of Fathom, compared to 7 levels on the
Atari 2600. After getting through all 9 levels you are presented with a
special message from the programmer.
TOUCAN'S TRIVIA: The manual for the
TI-99/4A version of Fathom actually
has the picture flipped around. On all other versions of the game the
mermaid's tail points to the right (such as on
the Atari
2600 Box). It is also interesting to note that the TI-99/4A
manual for Star Trek had it's picture
flipped around as well. The reason why TI flipped some of
the pictures around on their manuals is not known.
