It wasn't until a couple of hours ago that Jules sent me a link to 
your photos and I knew right away that it wasn't it (my ISP 
automatically bounces anything with a dyndns address in it).  The 
Bryant had a larger center hole and the disks were thicker.

CDC put them together with a controller and called them the 6603.  
Zoned recording--the inner zone had fewer sectors than the outer.
