Misjudged the rate in which the BE58 would descend to avoid the overflight. Update the BRITE to newer user friendly equipment. It's difficult to use; the graphics are poor compared to what we use and see with other media. It hangs on the ceiling making it more difficult to see because of the graphics.
Tower Controller indicated a loss of separation event claiming the BRITE equipment graphics and location made it difficult to observe needed information.
