   think I am done working on this   
   now use these rules for this combo of Powerbook G3 (Wallstreet II), Apple IIe   
   (1982), two AE drives labelled AEHD, AE controller card, reactivemicro   
   controller card   
      
   1) G3 and Sys 9.2 have trouble with ProDOS so avoid the twosome   
   2) AE controller card does 800k; not 1.4mb so stop trying to make it do 1.4   
   3) AE drive labelled AEHD does 800k and 1.4mb when used with the reactivemicro   
   controller card so use the reactivemicro card and park the AE card   
      
   with these rules things go as expected   
      
   addendum;  things for fun of it   
   0) appears AE had 3 cards; AE,  AEHD and AEHD+; I have AEHD   
   1) I guess Sys 9.2 was known to have ProDOS problems but Apple moved to OS X   
   and never fixed 'em   
   2) wonder why AE never made a controller card for AEHD drive that does 1.4?    
   Or is there a 1.4 AE controller card for AEHD drive and I missed it?  Or did   
   they just expect buyers to use the Apple Card?   
   3) But then I see AE sold AEHD in 1990 but Apple Super Card came out in 1991   
   so how could early adopters use the Apple Card?
