Doug- hello, not to be a pest, but I was about to list some accessories for my old atc-510 flight simulator on ebay. I searched the internet for atc-510 simulator, and only came up with a handful of results. One of them was a thread where you said you were looking for something for your 510. Please let me know 1) if you still have the unit and 2) if you are looking for any accessories. thanks for your time and sorry to bother you, Mike
