Cory, those are great suggestions. One of the problems I've run into is that Drive Setup (for 7.6 and under) wants to limit my partitions to only 4GB, even those that are not necessarily going to be used for the system. If I make a very large partition, the system - once installed - does not recognise it. So, would you recommend using Drive Setup to create a single 4GB partition leaving the other 70gigs unallocated? Is there a way to repartition the drive AFTER a system is installed on the first partition without losing the data on that single 4GB partition to make space for the 10/20GB partitions you recommend? I'm aware of this in the likes of OS X, but haven't managed to try it on System 7. I'll have a look at your links. Many thanks!
