HP C2502-66500 ScanJet ISA SCSI Interface Card 25-Pin DB25 Scanner Adapter Rev B

HP C2502-66500 ScanJet ISA SCSI Interface Card 25-Pin DB25 Scanner Adapter Rev B

The HP C2502-66500 is an ISA bus SCSI interface card designed to connect HP ScanJet flatbed scanners to desktop PCs via a 25-pin DB25 SCSI connector. This card installs into a standard ISA expansion slot and provides the dedicated SCSI host adapter interface required by HP ScanJet scanner models that do not use a parallel or USB connection. The board is marked Rev B and was manufactured in the USA, with an NCR 53C400A SCSI controller chip onboard.

Applications

The HP C2502-66500 is a dedicated scanner interface card designed for use with HP ScanJet flatbed scanners that require a proprietary ISA SCSI host adapter. HP ScanJet models from the early-to-mid 1990s — including the ScanJet IIc, ScanJet IIp, and related variants — relied on ISA SCSI interface cards like this one for connectivity to IBM-compatible PCs, as USB and native parallel scanner interfaces were not yet standard. This card is sought after by users maintaining legacy HP ScanJet scanning setups, vintage computer enthusiasts, and businesses or institutions still running period-correct workstations that require original HP scanner connectivity hardware.
