Micromys V3

Micromys V3 lets you use a PS/2 mouse on the C64, Amiga or Atari ST. USB mice can also be used, if they are shipped with a PS/2-USB adapter. Not all USB mice can use these adapters! Micromys V3 is not limited to specific mouse models. You can use any 2-button, 3-button or 3-button wheelmouse (Microsoft Intellimouse) with Micromys V3.

Connecting

Please switch off the computer before connecting anything in order to avoid damage to your precious equipment! Connect the PS/2 mouse to the 6-pin mini DIN connector of Micromys V3. The 9-pin Sub-D connector goes to the mouse port of your Amiga/Atari ST, or to one of the joystick ports of your C64. Note that most C64 programs consider control port 1 to be the "mouse port".

DIP switch settings

The two DIP switches set one of four modes of operation. After changing the DIP switch settings, you need to power-cycle the machine. Changing the DIP switches during operation may cause undesired operation, but won't break anything.


Micromys Dip on on.jpg
Put both DIP switches to the ON position for the 1351 emulation mode. This will let Micromys V3 emulate the Commodore 1351 mouse that was popular for the C64. Programs like GEOS, Pagefox, GoDot and Mr.Mouse will work. This is the setting that Prophet64 and MSSIAH users should choose.
Micromys Dip on off.jpg
Set DIP1 to ON and DIP2 to OFF for operation on an Amiga computer without any drivers. This mode will also let you use the (rather rare) middle mouse button that a few programs like DOpus can use. Wheel movements are ignored in this mode, but pressing the wheel will be reported like pressing the middle mouse button.

Set DIP1 to OFF and DIP2 to ON for operation on an Amiga with drivers for the wheel. The mouse will work just like any other Amiga mouse if the drivers are not yet started, so using the mouse in the early startup menu is possible. Wheel movements and pressing on the wheel does not have any effect until the drivers are started. Click here for a closer description and developer info.

Put both switches to the OFF position for the Atari mode. Please note that Atari never had any standard for a third mouse button, let alone a wheel, so any wheel movement or middle mouse button is ignored in this mode of operation. In this mode, Micromys V3 can be used on any Atari ST or Falcon model.

1351 Mode

Put both DIP switches to the ON position for the 1351 emulation mode. This will let Micromys V3 emulate the Commodore 1351 mouse that was popular for the C64. Programs like GEOS, Pagefox, GoDot and Mr.Mouse will work. This is the setting that Prophet64 and MSSIAH users should choose.

Joystick emulation mode

Just like on the original Commodore 1351 mouse, Micromys V3 can emulate a joystick if it's set to C64/1351 mode (both DIP switches ON). To enter this mode, hold down the right mouse button during power-on. Any mouse movement is now translated into joystick signals, so any software that can be controlled with a joystick can now be controlled with a mouse. The left mouse button will be translated to the firebutton of the emulated joystick. Wheel movements, middle and right mouse buttons will be ignored in this mode.

note: Today's optical mice are doing a self-test on power-up and do not pass on a mouse button that is pressed during power-on. This will probably prevent many mouse types from being used as a joystick with Micromys V3. Since a mouse is not a good joystick replacement anyway, we don't think that this is a major drawback. For the best gaming feeling, we recommend a Competition Pro Retro joystick.

Amiga Mode

Set DIP1 to OFF and DIP2 to ON for operation on an Amiga with drivers for the wheel. The mouse will work just like any other Amiga mouse if the drivers are not yet started, so using the mouse in the early startup menu is possible. Wheel movements and pressing on the wheel does not have any effect until the drivers are started. note: Today's optical mice are doing a self-test on power-up and do not pass on a mouse button that is pressed during power-on (let alone two mouse buttons at the same time). This will probably prevent many mouse types from letting you enter the early startup menu on a cold start of the Amiga. You might have to give Micromys V3 a few seconds after power-up to establish proper communication with your mouse, then reset the computer and hold down both mouse buttons to enter the the early startup menu.
