   What a twisted web we weave...   
      
   Notice they included the SCSI controllers, Intelligent Memory Mover, and   
   the Remote Maintenance Processor into the total... You can get either   
   ONE or TWO system processors, though my SWAG is a uni-processor is a   
   system/application processor, while a dual-processor has a system   
   processor and an application processor...

   "The Parallan servers are upwardly compatible and include the Parallan   
   Server 290, Models 10, 20, 50, and 60. The Model 10 has five processors,   
   including one 33MHz 80486 system processor, two RISC SCSI processors,   
   the bit-sliced Intelligent Memory Mover, and the 80C186-based Remote   
   Maintenance Processor (RMP). A 64-bit InterProcessor Bus, 8M bytes of   
   Error Checking and Correcting (ECC) main memory, 676M bytes of hard disk   
   storage, one dual-channel SCSI intelligent disk controller, a Micro   
   Channel bus with eight slots, and Parallan’s Maximum Availability and   
   Support Subsystem (MASS) are all a part of the Model 10.   
      
   The Model 20 has one additional processor beyond the Model 10, a 33MHz   
   Intel 80486 system processor. It differs from the Model 10 in that it   
   contains 16M bytes of ECC main memory, 1.3G bytes of hard disk storage,   
   a dual-channel SCSI controller, and a dual Micro Channel bus. The Model   
   50 has eight processors—two 33MHz Intel 80486 system processors, four   
   SCSI processors, the Intelligent Memory Mover, and the 80C186-based RMP.   
   It has the 64-bit IP-bus, 24M bytes of ECC main memory, 5.4G bytes of   
   hard disk storage, two dual-channel SCSI controllers, dual Micro Channel   
   buses with 12 slots, MASS, and one expansion enclosure. The Model 60 is   
   identical to the Model 50 except that it has 32M bytes of main memory,   
   10.8G bytes of hard disk storage, and three expansion enclosures."
