The Microbus MAT 915 is a PICMG 1.0 Single Board Computer built around Intel Pentium III or Celeron processors for industrial and embedded applications. This SBC consolidates core motherboard functions onto a single card that plugs into a passive backplane, eliminating traditional motherboard complexity while preserving modularity and serviceability.

– Key Features
• PICMG 1.0 passive backplane architecture enables modular CPU upgrades without backplane replacement
• Single ISA slot configuration option for space-constrained deployments
• Dual-output video with both analog and digital flat panel support
• Low-voltage differential SCSI for noise-immune industrial environments
• Watchdog timer for software crash recovery and system supervision
– Typical Applications
Industrial control systems, embedded vision platforms, point-of-sale terminals, rugged field instruments, and compact multimedia systems requiring video input/output with compact storage.
– Compatibility & Integration
Standard PCI and ISA peripheral cards integrate via PICMG backplane. CompactFlash storage appears as IDE, simplifying OS deployment. Multiple processor and memory configurations support diverse operating systems and legacy applications.
