First you download the V1.52 compressed files.
Then you need the Lionel loader software (?).
Then you unzip and copy the V1.52 files over to two separate black modules, (or "modifed" blue modules).
Then you basically follow the instructions on pages 75-76 of the V1.5 User Manual to load the new files into the CAB2 and Base2.
Is that about it?
Only thing is I can't see how you connect the black modules to a computer to load the files, since they don't use any standard serial or USB type connectors. How do you do this?
Is there a connection diagram somewhere?
I do have the Lionel "Y" harness that came with the #990 set. Do you use this somehow?
Thanks for any help.
