/**
|

|
|
The Atari Mindlink was an unreleased video game controller intended for
|
||
|
|
release in 1984. The Mindlink was unique in that one had to move the
|
||
|
|
muscles in one's head to control the game. These movements would be read by
|
||
|
|
infrared sensors and transferred as movement in the game. For more
|
||
|
|
information, see the following link:

|
||
|
|
|
||
|
|
This code was heavily borrowed from z26, and uses conventions defined
|
||
|
|
there. Specifically, IOPortA is treated as a complete uInt8, whereas
|
||
|
|
the Stella core actually stores this information in boolean arrays
|
||
|
|
addressable by DigitalPin number.
