GNP Computers CPCI SCSI to IDE Transition Board 1-502518 Rev B 68-Pin

GNP Computers CPCI SCSI to IDE Transition Board 1-502518 Rev B 68-Pin

The GNP Computers 1-502518 is a CompactPCI (CPCI) SCSI to IDE transition board that bridges SCSI-based CompactPCI systems to IDE storage devices. Manufactured by GNP Computers (also known as GNP PDSi), this board translates between the 68-pin SCSI interface common in CPCI embedded computing platforms and standard IDE drives or IDE-based storage. It is a Rev B board, date-coded 000807, and made in the USA.

Applications

CompactPCI (CPCI) is a rugged, rack-oriented variant of the PCI bus standard defined by the PICMG consortium, widely adopted in the late 1990s and 2000s for industrial, telecommunications, and embedded computing applications where hot-swap capability and mechanical durability were required. SCSI-to-IDE transition boards like this one were used in CPCI systems where the host backplane or controller communicated over a SCSI interface, but the target storage devices were IDE (ATA) drives — allowing less expensive or more readily available IDE drives to be deployed in SCSI-based CPCI enclosures. GNP Computers was a well-known designer and manufacturer of CompactPCI and VME single-board computers and peripheral modules, commonly found in defense, aerospace, telecom infrastructure, and industrial automation systems. This board would be relevant to engineers maintaining or upgrading legacy CPCI-based systems that require a SCSI-to-IDE interface bridge.
