Summary: A1000 and SCSI Host Adapter

From: Hichael Morton <>
Date: Tue Nov 26 2002 - 09:15:34 EST
Scenario: Manager purchased a Single-Ended SCSI (375-0005) card to use
with A1000s.  The Sun System Engineer handbook and other documents do
not list the 375-0005.  I asked for confirmation of this.

10 responses were received within a few minutes stating that, as the
literature states, the Single-Ended SCSI controller will not work with
an A1000.  The Differential SCSI controller is required; its Sun part
number is 375-0006.

Many "Thanks!" to all whom responded.

Thank you!
