Strange, on my 32 bit PC:s (running Windows XP and Mathematica 5.2 and 6.0), $MaxNumber is 1.9202246726923565854204690606`15.954589770191005*^646456887 I use (single) Intel Pentium 4 processors. Maybe you use AMD processors? So maybe you have not to invest in a 64-bit processor, just to get a larger MaxNumber. (I hope I did not kill your best argument for upgrading ;-) ) By the way, I note that Exp[Log[$MaxNumber]] generates Overflow, but Exp[Log[$MaxNumber/2]] is OK on my computer. I use that in a program, so I wonder if there is any other system where the last expression generates Overflow.
