so, you are not sure about the watts
=============================
That's correct, I couldn't find a reliable source that specifies the 
wattage of the power supply for the Digital Personal Workstation 500au. 
However, based on the technology available at the time and the size of 
the workstation, it's likely to be in the range of 200 watts to 300 watts.
