   But for the cost of a pint of warm beer, we might have a better answer...   
      
   I can remember the flash in the pan of VLB. Some implementations skimped   
   on buffering, and weren't reliable.   
      
   At some point, IBM would have evaluated it's efforts to support the   
   various bus flavors. ISA. PCI. MCA. VLB. RS/6000. S390. And a whole   
   buncha legacy big iron... Hell, AS/400...   
      
   I did see an IBM boxed VL SCSI controller, dunno if it was IBM built or   
   made for IBM. Lor, any comments?   
      
   I have noticed the Model 56 "local bus" comes off the CPU, shares the   
   SCS, and reaches the BIC. The Micro Channel is on the other side of the   
   BIC [and buffered by the BIC].   
      
   At this point, I am unaware of any IBM MCA system where the MCA feeds   
   directly off the CPU bus. Think of the DMA logic, the arbitration, and   
   other stuff [like memory controller].
