Already downloaded and installed, looking through my closet for a serial board! 
Of course, the black modules aren't available yet, so it's of very limited use yet...
You don't really need black modules. Only if you want to save an engine and load it on another system. You can do everything to your system via the serial cable.

from the manual (it's included in the download, Help-> How to use LSU)
With the purchase of a 6-37125 LEGACY Writable Utility Module, you can also use LSU to:
• Download latest software from Lionel’s website and update your LEGACY Base and CAB-2 Remote Controllers.
• Create new, customized Engine Memory Modules to use on any LEGACY layout. The LEGACY Writable Utility Module does not store LEGACY database backups. Customized engine modules do not include Train assignments or momentum settings.

John, even without the black modules you can still backup your engine database, edit the engines and write back to the base.
Except for upgrading the system and putting the personality files for several (up to 99) engines on one chip you will find the black modules are actually a kind of secondary feature. I like being able to edit my engines.
Good point, and it would be nice to have a backup. 
Cool more stuff to play with.
