I am trying to liquidate equipment from my employer that just went under. I
have figured out everything except this one thing..

We have two SUN Sparc 20's, which I know are pretty cheap. The thing is,
between them there are 5 GXtra server cards. These are the nifty doodads
that let you hook up multiple monitors as dumb terminals to a Sparc.

One box has 3 of these, and the other has 2. What are these things worth?
