PR Controller banging around

[WFWS]

I cleaned out my shop, and rediscovered my old Shopbot PR controller and power supply. Yep, I said PR. Not alpha, not PRS, the old PR. I bought a second hand PR several years back and modified it heavily, which included a new aftermarket controller. I stored the old Shopbot controller at that time. It was working when I put it away, so I assume it does now. It uses DOS based software, if you can imagine that.

What is that sort of thing worth, and is it useful to anyone these days? If so, I'll list it. Its doing no good sitting in my shop.

Thanks for any advice on this.
