	I quite sure this has been hacked around before, but here
    goes anyway.

	68020 vs. 32032 which is better to base your system around?

	(assuming the 32032 is available)

go ahead bug, make my day.

I like the 32032.  Simpler chip (less transistors == more reliable (?), MUCH
more orthogonal instruction set (better -> faster compilers, faster, more
compact object code), 32032 available now (6mhz version), along with fpu and
mmu.

Now, when the 68020, motorola fpu and advanced mmu become available, the
fanciest system you could build with motorola parts will probably outperform
the fanciest system you can build with (currently proposed) national parts.
You will pay for that extra bit of performance through the nose though.

National seems to have decided to do simpler components optimized to what they
consider to be the average use, rather than fancy parts that can be adjusted
to optimize your particular use.  In exchange, national was able to produce
their parts, while motorola is still dreaming.

No connection to mot or nsc, always my own opinions

The NS32032 is available *now*, which is more than you can say for the
MC68020.  Don't hold your breath for the 68020's memory management and
floating point units either...has Motorola announced when they should
be available?

I believe Motorola has said that the support chips for the 68020 will
be available "several months after the 68020".  In other words, just
this side of never.

And as Jan Gray reported, 32032's are available *now*.

I would like to see some benchmarks comparing the two processors, both
with and without floating point operations. Also, has anyone heard of
any enhancements or new chips by NS to combat the 68020?
