"The IBM PC model 5150 was announced at a press conference in New York on August 12, 1981" from http://www.cedmagic.com/history/ibm-pc-5150.html --Which is ABOUT 1982!
"The XT stands for EXtended Technology and was introduced in early 1983." >From http://alienc.netcentre.ca/gallante/ibmcpu/5160.html --Which IS Circa 1983! "The IBM PC/AT (for "Advanced Technology") was introduced in mid 1984 " >From http://www.digibarn.com/collections/systems/ibm-at/ --Which IS Circa 1984! I think one of the original posters was confusing the AT and XT designation as to a 1982 production date. I was just giving some approximate introduction dates for the first several models. My dates were correct in context.
