Still incorrect. ;)

It first showed up in Solaris, not SunOS.

Early directory services were rcp/ftp, in all their glory. :). Mostly though at the small school I was at it was moot. THE VAX we had was 100% ASCII terminals to access it, except if you were logging in from the Tops-20 box via telnet from one of its ASCII terminals. 

SunOS 4 definitely had YP. We used it in school when the Tops-20 machine was replaced by a boatload of 68000 machines running SunOS and Suntools... I can't recall if 3.5 also had it or not... it was later it changed to NIS.
