Bass Thumper,
There's two important information specification groups you cited. First there are the minimum operating system (OS) and hardware program run requirements. Second is the storage space required for the Pro, Mega and Ultra packages.
I do not remember anyone ever remarking or complaining about the minimum program run requirements. The fact is the minimum requirements are so low the program seems to be able to run on any operable computer using Windows. As with anything computer related, the faster the hardware the faster the program will run.
However package storage space, especially for the Ultra PAK, seems to be a constant concern that generates many questions within the forum. The questions are posted by both newcomers and long time users.
Because there are so many questions, I've posted a
+++ wishlist request +++ for a utility program that automates the process of moving Band-in-a-Box, RealBand and their associated content from primary to secondary storage drives.
