I only have Compendia back to the first Digital version, in 1995(1994?). I know what a "spider" dial is and looks like, but what was the effect of the CD, other than the pretty diffraction patterns? Possibly, a spider dial with no vertical gnomon? That would work well, for sure! And, since I define AOL throw-aways as "faulty" from the start, I have plenty of the required dial faces...
