+In this mode, the ikbd generates a record whenever the joystick position is
changed (i.e. for each opening or closing of a joystick switch or trigger).
The joystick event record is two bytes of the form:
keys. Any keys down at power-up are presumed to be stuck, and their BREAK
(sic) code is returned (which without the preceding MAKE code is a flag for a
keyboard error). If the controller self-test completes without error, the code
-0xF0 is returned. (This code will be used to indicate the version/rlease of
+0xF0 is returned. (This code will be used to indicate the version/release of
the ikbd controller. The first release of the ikbd is version 0xF0, should
there be a second release it will be 0xF1, and so on.)
The ikbd defaults to a mouse position reporting with threshold of 1 unit in
the mouse. After any joystick command, the ikbd assumes that joysticks are
connected to both Joystick0 and Joystick1. Any mouse command (except MOUSE
DISABLE) then causes port 0 to again be scanned as if it were a mouse, and
-both buttons are logically connected to it. If a mouse diable command is

9. ikbd Command Set
9.7 SET MOUSE SCALE
0x0C
- X ; horizontal mouse ticks per internel X
- Y ; vertical mouse ticks per internel Y
+ X ; horizontal mouse ticks per internal X
+ Y ; vertical mouse ticks per internal Y
This command sets the scale factor for the ABSOLUTE MOUSE POSITIONING mode.
In this mode, the specified number of mouse phase changes ('clicks') must
0x0F
This command makes the origin of the Y axis to be at the bottom of the

mouse motion. This causes mouse motion toward the user to be negative in sign
and away from the user to be positive.
