   either an ADF or image of the microchannel version. Pictures, or it didn't   
   happen. It was a thing to convert your PC, XT, Tandy 1000 ('uxwbill' video),   
   or PS/2 Model 25 and 30    
   to act like an Apple II - but would businesses do that with a microchannel   
   system? The lack of a known ADF is incriminating; All references to   
   microchannel seem to come from a single source.

   the author says (Errata #2 at the bottom):   
      
   "11/19/2002 - Major confusion! The machine I'm actually using is an IBM PS/2   
   Model 30/286. Earlier, I assumed the machine was a Model 55SX, based on   
   reading the front of the case. A reader from comp.sys.apple2 mentioned that   
   the 55SX is actually a micro    
   channel (MCA) model, and not an ISA. That concerned me big-time! So after   
   cross-referencing several of the parts in the machine via its FRU numbers, it   
   ends up that the machine is indeed a Model 30/286, but in an Model 55SX case.   
   How this occurred is    
   beyond me! I received the machine from a local hospital after their Y2K   
   clean-up, so anything could have happened to it during its 11-year lifespan."   
      
   That would explain the MCA-confusion...
