This distributed design enables the user to:

• Virtually eliminate contention among nodes for improved 
    application response time
• Provide optimal power to each functional area of an
   application
• Independently develop each node’s function
• Incrementally enhance the performance of each node
• Easily expand a system with the addition of new nodes for new application functions

MULTISel nodes contain:

Each of these components is implemented on a single circuit board. MULTISel nodes also can contain an Internal Processing Unit (IPU) a secondary computational processor — with its own Floating-point Coprocessor.

Multi-Function Processor

Several SelBUS and Multipurpose Bus boards are consolidated on the Multi-Function Processor (MFP) board. This board encompasses the following functions:

• Console port Seven asynchronous ports
• Line printer port
• Real-time clock and interval timer
• 12 external interrupts
• Two Small Computer Systems Interface (SCSI) buses — one dedicated to a fixed disk 
     drive the other for a magnetic tape drive and future devices

The MFP supports these functions without an expansion chassis. As an option, a second device interface card supports two 5 1/4inch floppy disk drives and is capable of generating an MP Bus

Dual-Port Integrated Memory Modules (DPIMMs) provide 2MB or 8MB of memory, DPIMMs feature two-way, on-board interleaving, which alleviates memory busy problems and improves memory access times in various applications. The second port of the DPIMM supports Reflective Memory DPIMMs can provide 16MB of memory and use only two Slots
