Acromag / Xembedded / Xycom XVME-955 Hard Disk/Floppy Disk VME Module

The Acromag / Xembedded / Xycom XVME-955 is a dual-drive VME storage module that integrates hard disk and floppy disk functionality into VMEbus systems. The module occupies two double-high VMEbus slots and connects directly to the P1 backplane for power and ground, while disk interface signals route through front-panel ribbon cables. It delivers reliable data storage for industrial and embedded VME applications requiring both magnetic disk capacity and removable media support.

Technical Specifications

• Drive Configuration: One 3.5-inch hard disk drive and one 3.5-inch micro-floppy disk drive


• Hard Disk Capacities: 85 MB, 127 MB, 240 MB, or 1.6 GB


• Floppy Drive: High-density 1.44 MB 3.5-inch micro-floppy


• Form Factor: 6U, dual VMEbus slot module


• Interface: IDE and floppy connectors; front-panel ribbon cable routing


• Power & Ground: Supplied via VMEbus P1 backplane connector

Key Features

• Integrated IDE hard disk and floppy drive subsystem in single module


• Multiple hard disk capacity options from 85 MB to 1.6 GB


• Standard high-density 1.44 MB floppy support for data interchange


• Direct VMEbus backplane integration eliminates external power supplies


• Ribbon cable interface minimizes front-panel footprint

Typical Applications

• Industrial control systems requiring onboard data logging and storage


• Embedded VME systems with removable media backup requirements


• Legacy VMEbus platforms transitioning to higher-capacity disk subsystems


• Systems requiring both fixed and removable storage in compact form factors

Compatibility & Integration The XVME-955 pairs with Xycom VME PC/AT processor modules, which provide the primary processing and IDE/floppy controller logic. The XVME-951 adapter module includes provisions for routing disk drive cables from processor modules to the XVME-955. The module also integrates with Adept Motion VME systems.
