   So my physical 1541 prevents the C128 from completing boot up when the drive   
   is powered on and serial cable connected.  If I kill the power to the drive   
   while the 128 boot up is hung, the 128 completes booting.  Same if I   
   disconnect the serial cable    
   while the 128 is hung on bootup.  And the drive does not respond to load   
   command, 128 reports drive not ready.    
      
   I opened the drive case, board is internally very clean, and no burnt or   
   bloated caps.  I am guessing one or more of the logic chips is bad.  Looks   
   like the MOS chips are from 1984.  I am using an aftermarket serial cable, the   
   cable pins look correct    
   when compared to online pics, and continuity pin to pin on each end is good.    
   I guess these serial cables are supposed to be pin to pin straight wired.   
      
   If I get some ambition in the next few days, I will use my scope to check for   
   activity on the logic chips.  My understanding is that with the scope ground   
   on a chip ground and scope lead on address or data pins, I should see high   
   speed voltage    
   oscillation, indicating logic activity...   
      
   Hate to give up on all my floppies, even if I pick up an emulator...
