Hi @as00502,

Googling for "PROC MIXED was introduced" I obtained this hit saying that in section 26.2.1 of this book the authors state that "SAS/PROC MIXED was introduced in 1992."

Yes, most sources say that MIXED was introduced in 1992.It was greatly changed, expanded, and improved over the following few years.
