The following quote was taken from Intel's web site (http://developer.intel.com/design/intarch/intel386/index.htm):
"The Intel386™ DX, EX, and SX embedded processors are based on the Intel386 architecture. All have 32-bit cores, and enhanced functionality for the embedded processor market."
Damion was right, the 386 is a 32-bit processor. Intel refers to prePentium processors as "Mature Processors" and I thought it was odd that they do not mention the 286. Anything before the 386 is referred to as a 186 (which is described as 16-bit). Never in my 15 years of using computers have I heard of a 186 computer!
