Hi Mike!

Read your comments on Basic on the MM/1.  Did not seem to jive with my
experiences so I duplicated your tests.  My CoCo is model 3 with 512k memory -
basically a 'vanilla' machine.  For the 68k tests, I have a PT68 model K4 which
uses a 68000 chip, has 4 megs of memory and runs at 16 MHz.  OS is version 2.3,
Basic is version 2.1.

I also had the tests run two 'VME' machines.  One machine was a 68010 running
at 12 MHZ.  The operating system for this machine is Version 2.2 and the
version of basic is 1.2.  No other tasks were running.

The second machine was a 68030 running at 25 MHz.  The operating system for
this machine is Version 2.3 and the version of basic is 2.3.  This machine has
a math coprocessor and an indeterminate number of other tasks were active.

             These are the results (in seconds)
    (I included your results on the MM/1 for comparison purposes.)

CoCo  MM/1   PT68K4   68010      68030      Conditions
  4     3       1        3          1       As written (k=1000)
 40            12       26          8       k=10000
 78    59      23       52         14       k=20000
 10    13       8        8          2       k=1000 (Changed integers to real)

Note that in all cases the PT68 was faster than the CoCo.  Marginally when
using real numbers and substantially when using integers.
