Hello ExcelX,
Unfortunately, there is no meaningful way to interface with the 9081 without having the correct versions of LabVIEW (at least 2011) and NI-RIO (at least 4.0). It does run windows, so you could in theory boot it up in Windows and attach a monitor to it, but you wouldn't be able to run any code on it.
You could download the trial version of LabVIEW 2011 and use it with your 9081 for thirty days. But I recommend just upgrading to LabVIEW 2011 - the 9081 is a powerful (and expensive) CompactRIO.
