I have happened onto an old spaceball, model 2003, it has no cables with it and looks to need a power source. I have used a 3003 in the past, but it must have drawn power from the serial connection, so I am guessing they require 5-9v in the 100-300 ma range. Anyone use/know about these things? - to clarify, this device has a base shaped like a question mark on it's back with a 2.5 ball in the cup of the base, buttons on the top. Looks to be new, but seperated from documents, cables and software.
