Future support of unsupported now mice
Yet some another mice, like A4Tech WOP-35, can be Intellimouse (and even Explorer) compatible, but have additional features like two wheels, feedback (Logitech iFeel), etc. Some mice can have even different ideology - like Maxxtro with «joystick» between buttons. Additional features of these mice can't be used with current version of ps2m, but things have characteristic to change :-)
Compatibility with Amigas and software
Because of this device has two interfaces - to the computer and to the mouse, I must describe both questions.Compatibility with Amiga is not a problem - device will work with all current Amiga models, from A1000 to A4000 and A1200. You can even try to adapt it for Atari ST or any other computer, where was used bus mouse interface.
WBM utility was compiled for 68000 and requires only 2.0 OS. If you don't use wheel(s) - you can use controller even under 1.x OS. Controller succesfully works under Linux and any other operating systems on Amiga hardware - not only AmigaOS. If you want - you even can write wheel support to any OS. All details can be found in WBM source code.
There is some small problem with Scala: because of parallel joystick feature and usage of fire0 at mouse port for custom Scala hardware, PS/2 controller will be disabled after start of Scala. It is not a noticeable problem - you can enable it again by one mouse click. If it disturbs you - my PS/2 controller (from version 1.5) has special feature: if you will hold right mouse button pressed during start of Scala, parallel joystick feature will be disabled during all following session of your work. If you want enable it again, for game as example, you can switch power off/on, or simply disconnect/reconnect mouse.
