    My Reflections 4/X version is old, and it only knows about Windows NT
    4.0 and earlier. Reflections 4 says that I have to install a special
    DLL for it to use the LK450 layout, but that also appears to have side
    effects for the Microsoft side. The script is also refusing to run on
    Windows 2000, simply stating it is prohibited from doing something. I
    have not yet tried Reflections X.

    So I will probably leave that alone. I do not have time to try a direct
    keyboard connection right now.

    I need to get a copy of the HP Pathworks 32 product for home use and see
    if that works.

    I can not get the autoscan feature to work.

    I can not find anything that admits to how long the cables are.

     From a crude eyeball estimate the cables look to be about 5 ft long.
    The instructions state that 8 ft is the longest that a video signal can
    be reliably delivered. But these cables are definitely not 8 ft long.

    There is no reason that the body of the switch has to be anywhere that
    it needs to be accessed. No buttons at all, just some LEDs that tell
    you which screen you are looking at.

    The instructions indicate that with a F1D084 CAT-5 Extender can be used
    to extend the length up to 500 ft.

    There also appears to be 4 port models and USB only models.

     From the FAQ in the manual:

       Q: What operating system does the Switch support?

       A: The Switch will support any operating system that runs on a PS/2
          platform, It will also work with Sun(tm) and Mac(r) operating
          systems using the appropriate adapters.[snip] Operating systems
          include but are not limited to, DOS, Windows 95, 98, 2000, Me,
          NT, XP, Linux, and Novell NetWare 4.x/5.x.

    But this one took my by surprise as I have been using all three buttons
    on my digital 3 button mouse since I got this thing and they work fine
    on VMS.

       Q: Does the Switch function with the Microsoft IntelliMouse?

       A: Yes, the Switch will function with Microsoft, Logitech,
          Kensignton, as well as with all Belkin mice. The Switch
          will support only 2 mouse buttons. Please contact Belkin
          Technical Support for any compatibility questions you may
          have.
