This information was removed from the artilce because it was not correct.  Even though this happened it happened much later and yes it was the first multiprotocol router,  Leave here as a reference as I read notes that say the History section was too complex.  Could someone advise?  (talk • contribs •  count) 

 as part of their contract to build out the original Arpanet.  The first multiprotocol router was created at Stanford University by a staff researcher named William Yeager  in January of 1980.  His boss at the time told him that he was the "network guy" and to find a way to connect the computers in the computer science department, medical center and department of electrical engineering.  He first wrote a network operating system and routing code to run on a DEC PDP11/05.  He used Alan Snyder's Portable C compiler but it generated too much code so he modified the compiler to improve the code generators.That still wasn't good enough so he wrote an optimizer for PDP11/05 assembler that reduced the code size further.
