This controller is basically like new. All leads are intact and the unit has seen only mild service for a total operating time of perhaps 20 minutes.
I thought I was interested in developing a robot, but after a few attempts, I discovered it wasn't as easy as it looked. Let my bad luck be your good fortune.
This unit comes in original packaging with the two serial plugs to fit the unit. The CD ROM is included.
Retail at Robot Marketplace is $495. I will ship to you in the contiguous U.S. for $375.
I can email photos for your inspection.
