   I'm a bit off here, sorry. The question I now have in mind is: is SCSI between   
   CPU and MCA better than SCSI on MCA, nicely packed between all other   
   MCA-devices, on one bus? I mean, local bus operations should impact MCA   
   transactions and vice versa,    
   probably affecting the overall performance Oo

   graphics adapter. On a 3-slot VLB Board you had one busmastering and   
   accordingly 2 secondary slots you had    
   to address using more than one card, especially with a SCSI/IO-Cards. With all   
   three VLB slots filled, it was some kind of a gamble if the system was stable,   
   even with 40MHz :-/ VLB was very card-dependant.
