It certainly wasn't any Microsoft operating system.  Microsoft was at 
least ten years late to the party.

If you define "internet access" as "having TCP/IP", it might have been 
BSD 4.1a, which included the crufty BBN TCP/IP code, and was released in 
1982.  ARPANET switched from NCP to TCP/IP on January 1, 1983 ("flag day").
