Barely used AHA-2940 Ultra host adapter kit with 50-pin connector cable
suitable for Ultra SCSI narrow drive interface. Ultra
SCSI speed for demanding professional
applications and high-performance peripherals.
Double the transfer rate
Using UltraSCSI technology, the AHA-2940 Ultra host adapter doubles the
maximum data transfer rate on the SCSI bus from 10 MByte/sec to 20
MByte/sec. By increasing the throughput rate between peripherals and the
desktop system, the AHA-2940 Ultra adapter accelerates system
performance and user productivity.
Ultra SCSI interface 20Mb per second synchronous data transfer rate
Extended translation supports drive capacity up to 8GB per disk 50-pin
high density connector
