However:  at least two companies are expected to come out with x86 (x >= 3)
clones this year (AMD is apparantly sampling the part now, and all
indications are that Cyrix will have something before the end of the year [I
hope! 8-)]), maybe more.  Since the second source people are the ones who
brought out the 20Mhz '286...

Also note, for the curious, Nexgen is doing a high performance *86 clone;
originally, it was supposed to be a '386 clone, but they may have thrown in
the extra few instructions to be '486 compatable.  I think it's supposed to
be two to three times faster than the '486, at the same clock rate...
