The adapter card converts interfaces, allowing compatibility between different SCSI connectors. Some conversion cards adapt male to female connectors, while others convert a 50-pin interface to a 68-pin interface, enabling 50-pin low-speed SCSI devices to connect to a 68-pin SCSI interface. The SCSI interface supports both synchronous and asynchronous data transfer. The synchronous transfer rate can reach up to 10MB/s, and the asynchronous transfer rate can reach up to 1.5MB/s. Note: Appearance may vary slightly between batches, but this does not affect functionality. Specifications: Color: Green Material: PC + Metal Compatibility: SCA & SCA-2 80-pin Note: This is a 50-pin IDE interface, not the 40-pin or 44-pin IDE used in standard computers. It is not compatible with ordinary computers. Package Contents: 1 x Adapter Card Note: Other items not included.
