I just purchased a CDS pick pocket machine US0320-002. 12-2000. After taking it apart and cleaning it trying to figure out what is wrong noticed that there is nothing plugged into the motherboard spot on the board in the back. I have never worked on a CDS machine before and just did a real quick glance inside before I purchased. It was only a 100 dollars and figured I could get that back just parting it out. I would like to fix it so any help locating a mother board would be appreciated. Not seeing much information on CDS machine so I am a little nervous that I bought a 100 dollar large paper weight.
