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").
