Part 11 : Joysticks
The built-in software in the computer supports either one or two joysticks. These are
treated as part of the keyboard, and as such, may be interrogated by INK E Y and
INKEY$.
Note that in the majority of cases, the main 'fire' button on ajoystick is interpreted as
'Fire 2' by the 6128.
The functions JOY (
Ql)
and JOY (
1 )
enable direct inspection of the first and second
joysticks repectively. The function returns a bit-significant result which indicates
the state of the joystick switches at the last keyboard scan.
The table below indicates the values returned by both joysticks. The JOY values are
followed by values for use in statements which take key numbers as parameters (i.e.
INK E Y and KEY D E F).
