Are these worth anything?

Yes, they have value. Do some google searches, you might be surprised. I recently sold off a working Ace Pulse Commander and an unknown condition Micro Avionics single stick system. Was very happy with what they sold for. Probably could have gotten more on eBay, but sometimes the quick sale is the best way.

Without receivers they probably aren't worth much. Like someone above said there are plenty of them around. Many people like to use them in antique aircraft but they have to be working and that means a receiver.
