Mel, 72 MB would be required for a Pentium 200MMX, in which the Fritz 5.32
engine would run at slightly over 200 KN/S.  My machine is a regular Pentium
200, which runs at about 150 KN/S.  I may be wrong, but I think that the rate at
which the hash tables fill up under the Fritz interface is directly proportional
to the KN/S of the particular engine.  Hiarcs 7.32 runs about 10X slower than
Fritz 5.32, thus the hash tables fill up at 1/10th the rate of Fritz.
