[quote=Primeinator;223525]I think all of those exponents have been factored past 62 bits (which, if I remember correctly, was the limit of what your oldest machine is capable of).[/quote]It's a matter of the default limit in the software, rather than a machine hardware limitation.

If the machine is so old it can't run anything later than Windows for Workgroups 3.11, the default limit in the (ancient) WfW3.11 version of prime95 would apply.

Thanks for this information. It helps me to understand the process much better!
