I think you mean before 1982.

TCP/IP was deployed starting in 1982. NCP was deprecated (removed from the
ARPANET) January 1, 1983, but TCP/IP was implemented (and deployed) prior to that.

It really wasn’t, but even if you just want to count from TCP/IP forward, 1983 isn’t the correct date. 1983 was when we 
turned off NCP. It wasn’t when we turned on TCP/IP. The turn on of TCP/IP occurred over several months, so there’s no 
particular date that can be assigned to it.
