   Using said technique allows me reading and comparing the /internal/ Miami   
   registers of the Ultimedia Video (ID 8F96) and SSA Adapter (ID 8F97).   
      
   Reading some internal registers of the SSA shows plausible values. Reading the   
   Card ID register returns the card ID, and register contents change with   
   address incremented.   
      
   Reading the same registers on the Ultimedia Video returns all 0x1FFF0050 for   
   just any address, no matter if internal or external to MIAMI.   
   Reading standard Micro Channel accessible registers through the IO space shows   
   reasonable content though, also compared to the SSA.   
   Interestingly, 0x1FFF0050 looks like an ADDRESS inside Miami's local space   
   itself! But it should not appear there as a VALUE.   
      
   Looks like something is wrong on Miami or it's external local address space.   
   How is it even possible for any external component next to Miami, like a CMOS   
   buffer, to override Miami's /INTERNAL/ register values?   
   I would assume, inside Miami, the internal addresses like card ID register   
   would be separated from the external local bus' address space.   
      
   Miami toast?
