Micromys V5
PS/2 Mouse Interface for Amiga, Atari ST/TT and Commodore 64/128
Micromys V5 is the long-awaited successor to Micromys V4.
The new version now supports more computers than ever before: Amiga, Atari ST/STe/TT/Falcon, C64, VIC-20
and the Atari 8-bit series. With a total of nine different modes of operation, Micromys V5
is probably the most versatile mouse adapter on the market.
Micromys V5 uses the proven automatic computer recognition of its predecessor
without the need for DIP switches. The adapter figures out most computer environments
automatically, and choosing a mode of operation is done by holding down one or more
mouse buttons during power-up.
Depending on the computer Micromys V5 is connected to, two or more of the following modes
of operation are available:
Amiga Wheel Mode:
Without drivers, this is a 2-button mode. Wheel and middle-mouse button can be activated
with the Micromys driver. No further connections to the Amiga are required: Wheel and
middle mouse button data are all transferred through the same mouse port, and the
joystick port remains free.
You can find the driver download in the Wiki.
Amiga 3-Button Mode w/o Drivers:
This is a completely driverless mode of operation. Programs that support the "native"
middle mouse button (for example Directory Opus) will work without any special additional software.
Atari ST/STe/Falcon:
The Atari ST uses two buttons only. Middle mouse button and wheel are ignored in this mode.
1351 Emulation:
The Commodore 1351 proportional mouse has become the de-facto standard for a proportional
mouse on the C64. Introduced with the GEOS operating system, it was quickly adopted by other
programs. The popular music programs MSSIAH and Prophet64 work best in this mode. Micromys
even adds to this standard by supporting the mouse wheel of a PS2 mouse.
Joystick Emulation:
Even if a program is not written for a mouse at all, this mode of operation can make a
mouse available to joystick-only programs.
Atari Trak-Ball CX22:
The Atari CX22 was the first of its kind. Although games that support this trackball
are rare, the experience of controlling the game with a PS/2 trackball exactly the way
it was meant to be is outstanding.
Paddle Emulation:
While paddles are hard to find these days, emulating paddles with a mouse provides a
whole new experience to games that are typically played with these rotary-type input
devices: Tests confirmed that variants of the "Blockout" game feel very
natural being played with a mouse.
Koala Pad:
This early graphics tablet was initially made for the C64, but can also be connected
to the VIC-20 and Atari 8-bit series. Programs that make use of this pad were so early
that they could not have possibly been written for a proportional mouse. However,
emulating this tablet with a mouse provides full proportional mouse support to these
old programs.
NEOS Mouse:
The NEOS mouse uses a fully digital interface, making it slightly cheaper than the
original 1351 mouse. Some programs are exclusively written for this type of mouse,
and with a small modification of the hardware, it was even possible to connect
this to the VIC-20 without blocking parts of the keyboard. Micromys V5 also supports
the NEOS mouse protocol, and even automatically makes required changes to the
protocol if a VIC-20 computer is detected.
