Overview
The HP 9000/742i Sidewinder were VME-based single-board computers (SBCs). Based on the HP 9000 715/50 workstation, they were integrated onto 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.
The HP 742rt version of these VME computers was designed for the HP-RT realtime operating system.
