) with built-in networking called the
SUN workstation, a name derived from the initials for the
Stanford University Network. It was inspired by the
Xerox Alto computer developed at the
Xerox Palo Alto Research Center. Bechtolsheim was a "no fee consultant" at Xerox, meaning he was not remunerated directly but had free access to the research being done there. At the time,
Lynn Conway was using workstations to design
very-large-scale integration (VLSI) circuits.
Bechtolsheim's advisor was
