Unfortunately, when I retired and moved from OH to TN, I lost my connection to some really good rework techs who could have straightened this out for me in less than 5 minutes! Also unfortunate, I don't have a hot air gun and possibly the skills needed to do this without melting the heck out of everything! I did order a few 24 pin, dual row headers to possibly recover the original board, but that can wait
On the bright side, I found that original motherboard is still showing as available at Lionel! I didn't see it on my first look because of the usual goof I make - I put dashes in the part number, and Lionel's website is not smart enough to figure out what I wanted. My 2nd attempt was indeed without dashes, and I quickly found the board for $28.00. I also checked the 692-PCB1-11E that Bob was kind of enough to point out, and it costs $32.00 and is out of stock - I believe it may have worked, but since Lionel actually has the original in stock, I'm done!
Thanks for all your help and insights. I'm looking forward to getting my newly acquired Phantom II on the tracks and running again - it is in absolutely pristine condition!!
Sure hope the mb I get from Lionel doesn't look just like this one!
