Hi all together,
concerning the question : ''Where can I find the software for version 1.3?''
An answer from the opposite side of the Atlantic ocean.
V1.3 had a bug that prevented a reasonable operation of Legacy in the 50Hz environment , as for example in use in Europe.
This bug was corrected in release 1.4 that followed shortly after 1.3. As consequence 1.3 disappeared in the Lionel webside, so a download of this release was and is impossible.
Regards
Albrecht
