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.
