We're taking a few days off. Orders can still be placed and
will be shipped (albeit a little slower), but there will be
no support until September.
There are currently shipping restrictions imposed due to the
SARS-CoV-2 pandemic which may lead to delays of shipments
outside of Europe.
PS/2 Mouse Interface for Amiga, Atari ST and Commodore 64/128
+++ No longer available, please have a look at
The new version of the Micromys interface comes without Dip switches for
its configuration, the adapter figures out most computer environments
automatically (you may need to press a mouse button in certain cases, though).
Here are the available 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 the driver from www.micromys.de
- Amiga 3-button mode without drivers:
User keeps middle mouse button (or wheel) pressed while switching the Amiga on.
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
- 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 it must be covered. If the user wants
to use joystick port 2, then Micromys must be attached to port 2 after power-up
and 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.
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.
In order to deal with space constraints on every desk, the Micromys V4 comes with
a long cable. 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.
