Micromys V4
Micromys V4 is the second generation of Micromys which implements a highly sophisticated auto-detect function of the host computer, so DIP switches are not required any more. Further, the case has become a lot smaller, and we have increased the length of the cable, which makes using the adapter on Atari ST and Falcon a lot easier.
Micromys V4 of course retains the high compatibilty of its predecessor, the Micromys V3 adapter. USB mice supporting the PS/2 protocol also work with the Micromys adapter. These are usually shipped with an adapter from USB to PS2.
In order to deal with space constraints on every desk, the Micromys V4 comes with a longer cable than it's predecessor. This design allows installation on every narrow desk, even when a bulky USB-PS/2 adapter is being used. Please note that due to the space constraints around the Amiga 600 mouse port and port 1 of the Commodore 128, an additional adapter with a smaller plug or modification of the Micromys plug is required.

Modes of operation
Amiga wheel mode
Just plug in and switch on. Device will auto-detect that it's connected to an Amiga and switch to 2-button mode with wheel support. Wheel and middle-mouse button can be activated with our driver. No further connections to the Amiga are required: Wheel and middle mouse button data is all transferred through the same mouse port, and the joystick port remains free.
Amiga 3-button mode without drivers
Since you don't have DIP switches on Micromys V4 any more, the 3-button mode for Amiga computers is entered only by holding down the middle mouse button while the computer is starting. This will disable the wheel functions of Micromys V4, but enable the middle mouse button that does not require any driver. In this mode, Micromys will emulate a mouse just like the rare 3-button mice that have been shipped with some A3000 models. The middle mouse button is supported by programs like DirOpus 4. This mode stays active until the next power cycle. A machine reset does not alter the mode of operation - only a power-cycle does.
Atari ST/STe/Falcon
Just plug in and switch on. Micromys will auto-detect that it's connected to an Atari and switch to that mode. The Atari mode supports two mouse buttons, additional buttons or a mouse wheel are ignored.
The following models could not be tested, but should work flawlessly with the Micromys adapter anyway: Atari Stacy, Atari TT 030, C-LAB Falcon, ATW (Atari Transputer Workstation 800 - ABAQ).
C64 or C128 in joystick port 1
This is the usual port for a 1351 mouse. Most programs use it for the proportional mouse, because the GEOS operating system expects the mouse there. If Micromys V4 is plugged into port 1, it detects the machine and switches to 1351 mode. Should the user hold down the right mouse button during power-up, the unit goes to joystick emulation mode, just like the real 1351 mouse would do.
C64 or C128 in joystick port 2
This is a rather unusual port for a proportional mouse. However, the popular music programs MSSIAH and Prophet64 use the mouse in that port, so we're also covering this mode of operation. If the user wants to use joystick port 2, then Micromys must be attached to port 2 after the program has been started. The program must be set to use the mouse, and then the adapter can be attached to port 2. Since auto-detect in port 2 is highly depending on software (thus may not always work), Micromys V4 can be configured to be C64-only by removing the auto-detect jumper inside the case. Once the jumper is removed, the auto-detect sequence is bypassed and the unit will work in C64-only mode on any port of any computer. This will also let you use the joystick emulation mode on other computers than the C64.

Developers
For some computers micromys provides support for additional buttons, which needs additional software support. Look at the Micromys Protocol page for details.
