	That should be easy to explain.  Assuming 16 bit numbers on
the Z-80 the maximum integer is 2^16-1 = 65,535.  Assuming 32 bit
numbers on the M68000 the maximum integer is 2^32 - 1 = 4,294,967,295.
So, assuming nothing funny was going on, the TRS-80 II was only
doing the loop 65,535 times and the Apple Lisa did do the loop
10,000,000 times.  BTW it took exactly 16 seconds on a unloaded DEC-20
written in Pascal (unoptimized).
