While I won't bet the ranch G.'s above cannot be made to work, all
the manuals and info I have on Mirror Disc/iX sez that the two
spindles in a mirror pair have to be an EXACT match in every way
(at least in every detectable difference, whatever that is)...  If the
two discs ID themselves with different model numbers, I'm relatively
sure that alone will prevent inserting the spindle as one side of a
mirror pair....    If anybody thinks I'm wrong about that, I would be
interested in hearing any evidence to the contrary....
