   Let me be more klar. SE.   
      
   How many IBM MCA SCSI controllers used a short PCB?   
      
   IBM SCSI/A (short)   
   IBM Fast SCSI/A (Patriot, NOT made by IBM)   
   IBM F/W SCSI (Corvette)   
      
   One raisin, possumbly, for the differential SCSI to use a Type 3 card   
   (full length, but not Passplay) is the need for the jumper header for   
   the high availability function.   
      
   There is one other adapter that uses the HPDB50 external connector, the   
   FC (2420) SCSI-2 Differential High-Performance External I/O Controller   
   (Type 4-2).   
      
   One issue I have findting out more on RS/6000 adapters is that the   
   announcement letters are usually for a system. So you have to wade   
   through a lot of announcements to findt the earliest availability of a   
   specific adapter.   
      
   You can search for the FC, but...
