Polymorphic Systems

It is amazing what can be found by looking around :). I had a box of "stuff" from Polymorphic Systems that I finally got around to checking out. I didn't realize that Polymorphic made a keyboard, but I have a metal chassic with "Polymorphic" on it and about 6 keyboard assemblies that fit inside. I also found a front panel to a System HD/18, a number of "new" System 88/DS front panels, a System 8810 front panel, various back panels, and enough wooden sides for another 5 computers or so. All of the front panels have cutouts for full size 5 1/4" drives. Maybe this will be the kick in the ... seat :) to get me going and backing up all the Polymorphic disks (8" and 5 1/4" totaling probably a couple of hundred disks) including source code and documentation for their products. Does anyone know what the HD/18 and 88/DS systems were all about? I've got another box someplace that holds a pair of 8" drives with Polymorphic logo on it, but I haven't had time to look through all the engineering documentation to find out what it is.
