Key Features

1. Flexible Storage Configuration
   • Combines floppy disk, IDE hard disk, and optional flash drive in one compact 6U slot.
   • Configurable for floppy-only, hard disk-only, or dual-drive operation to match system needs.
2. Passive VMEbus Design
   • Operates as a passive board with no active circuitry, reducing power consumption and failure points.
   • Connects directly to VMEbus P2 pins for power and user-defined I/O, ensuring compatibility with all standard VME chassis.
3. Industrial-Grade Ruggedness
   • Wide operating temperature range (-40°C to +85°C) supports deployment in extreme industrial environments.
   • Ruggedized components and compact form factor ensure resistance to vibration, shock, and electromagnetic interference (EMI).
4. Easy Integration & Maintenance
   • Single-slot 6U VME form factor fits standard industrial control cabinets without modification.
   • Hot-swappable in compatible VME chassis, enabling drive replacement without system shutdown.
   • Simple screw-terminal connections for storage devices, simplifying field maintenance.
5. Legacy & Modern System Support
   • Backward-compatible with legacy GE Fanuc VME processors (e.g., VMIVME-7750, VMIVME-7650).
   • Flash drive option enables migration from mechanical storage to solid-state reliability in modernized systems.
