     Special CAD controllers and extremely  large  databases
are  examples  of  a  rare  exception, rather than the rule.
Attacking National for only providing  24  bits  of  virtual
address  is  not only unfair, it is completely unreasonable.
People that use that kind of memory  also  need  specialized
hardware  to  give  the speed they require. If I was looking
for a CAD or Dbase system that needed >  16MB,  you  can  be
damn  sure I'm not going to go with any generic minicomputer
processor such as the 32032 or 68000. I'm going to need FAST
memory,  and FAST dedicated graphics and array processors if
I don't want to wait years for results.  The 68xxx  and  the
32032 just don't have the MIPS for that sort of work. I'd be
looking at large mainframes or dedicated workstations first.

     You can find faults with any processor you look at. The
32032  is  a  milestone in design, not only for the MMU, but
also for it's rich and higher language oriented  instruction
set.  Cutting it down is like cutting down a Porsche 924 for
not being a Ferrari Boxer.  Certainly it's not. But look how
much the other costs.
