	This is all fine. I neither agree nor disagree who has the 
    better chips. However , I do protest most vehemtly about  you 
    claims!!

	Sure a 68020 is faster, better (fill in blank) than a 80286
	One is a 32 bit machine, the other is a 16 bit. What I *am*
	going to ask you to consider is that in some respects the
	68000 is better than a 286 and in some a 286 is better than
	a 68000. In motorolas' own words.. Lets compare oranges
	to oranges not some other fruit, Ok ?

    Also, lets note for the record that motorola *still* is
    not producing massive quantities of the MMU unit designed
    to work w/ the 68020. Intel, however now has a 386.  You
    can go buy one today.  I therefore suggest that the real 
    definition of MMU is "mythical management unit".

    So, if one asks "the" question. Which is the better processor ?
    One should qualify... is it in silicon yet ?

    I have so far made my choice and it is neither.. when the
    68030 appears, I will rethink my decision.
