   Late Saturday evening, I blundered into a thought.   
      
   For those of us frantically trying to unwrap the mysteries of planar   
   ADFs, there are functions NOT contained in the Pnnnn, Dnnnn, and Snnnn   
   ADFs, yet when you run System Programs, shucks, them there Built-In   
   Functions is thar! Yuck, yuck! Long pull on the jug o' Slivovice...   
      
    From a very crude probulation of SC.EXE from the [so boringly] common   
   Model 90/95 diags disk, I >think< the common functions are in SC.EXE,   
   and board-specific functions are in the planar ADFs.   
      
   I have seen the four [!] Diskette Drive Types and planar/system board   
   SCSI controllers. Possumbly more. It would be sensible to stuff common   
   interfaces into SC.EXE and minimize the size / complexification of the   
   system-specific ADFs.   
      
   My apologies for a lack of dis-assembly, but I'm not smart. Must have   
   been the mandatory pre-frontal lobotomy that comes with field grade...   
   Remember, "A lobotomy brings them home every time"...
