The PortaSCSI provides a noise-free signal path, which means you can count on getting accurate data to and from your peripheral quickly. And you can be assured of getting the same reliable performance, whether running one CD-ROM drive or a daisy chain of seven peripherals.

Rugged design

The PortaSCSI is made to survive in the challenging portable environment. All PSS products are designed to tough “field service” specifications and have been tested in insurace “claims processing” applications. Since you and your portable computing devices are usually on the move, you need an adapter that is durable. The PortaSCSI is bonded to protect the internal components under the roughest conditions. Combined with the latching cable connector, you’re sure to stay connected and running.
