I have read many previous posts on the problems with the original releases of the backshop. I have some additional questions.
I purchased this item when it came out, just getting around to operating it. Mine came with Operation Addendum 72-2918-252 04/99. Backshop working fine convention mode with the exception of smoke unit not working on test bench. Smoke unit came with funnel installed. If reading correctly, smoke unit only works in command mode unless you change around the 3 pin connector. Is that correct? I believe I have an updated mother board from the original issue. How does one know if they have an updated board? Were several upgrades made of the board?? If so what changes/ enhancements made? I have seen couple videos on you tube(one by PRR_B&O FAN), and the sound of the machinery run has bells & grinding sounds that mine does not. Also in the PRR_B&O FAN video lighting was added with a rail inserted into each light socket from one end of backshop to the other end. Was this done by Lionel in a later release??
Thank you for any info anyone can provide.
