4.9 HP 9000/742i VME Workstation
4.9.1 Overview
The Sidewinder is a so-called Single Board Computer (SBC), based on VME. It features basically the
same core electronics as the 715/50 on a single board, but has fewer expansion possibilities — it takes
only a small amount of RAM, has no on-board expansion slots and graphics hardware (serial console
has to be used). The SCSI I/O is routed through the VME-P2 connector at the rear. Since the board
features a VME controller it is able to talk to other VME devices on the same bus (and control them).
