Overview
The HP 9000/742i Sidewinder were VME-based single-board computers, SBCs. They had the same core electronics as the 715/50 workstation on a single board with fewer expansion possibilities. SCSI is routed through the VME-P2 connector at the back of the board. Since the board features a VME controller it is able to talk to other VME devices on the same bus and control them.
