In this thread, we will discuss about the way to interact with the Apple IIgs. This will cover the following elements:
- Keyboard
Shall we use the well-known $C000 softswitch or use ADB?
- Joystick
How do we interact with the joystick ($C064...), an 1 MHz interface running on a 2.8 MHz machine?
How do we calibrate it?
- Mouse
Shall we also use the integrated softswitches or go with ADB? Can we?
And...
- Toolbox
Yes, there are plenty of tools that deal with the I/O of our beloved machine. What is the advantage of Window Manager's TaskMaster call compared to the _GetNextEvent call? What about the _Button one?
Everything will be covered based on some existing code (collected from several different 8-bit and 16-bit software) and some tips will be given (how do I flip the X or Y axis of the joystick?)
For the Apple II gamers, you should have noticed that some games use "asynchronous I/O" (eg. Karateka) putting the I/O data in tables, for use when needed by the game, instead of waiting for the I/O data to be available, we will also cover that.
