Just watched the video from Lionel on how to upgrade to 1.5. My question is can I upgrade from 1.3 to 1.5 and skip 1.4? Or do I need to do 1.4. The instructional video was great. Also I am using the cable that came with the 990 to connect to a TMCC base. Can you get another cable?? Or do I need to by that USB cable? You can get them on Amazon for about $27.00. Thank you I remain, Ed Powers.
