yes.. those are common cathodes.. (at least by link & auction description) 
What is the difference between the 11 pin and the 12 pin?
(12 pin version Eagle symbol is was attached in .sch & .brd files above)
So in general.. I should just be looking for a normal (common cathode) 11 pin 3-digit display/unit.. right?
(I need to find an Eagle symbol now too!) LOL
