The QQ Baby is a Taiwanese LCD cab by Weche. Same company that did the OK Baby. Or it should be the same company given it's identical name, origin, and business. I've never seen one in person in Taiwan before though, at least not in the biggest arcade chain (Tom's World) or any of the local places I'm aware of in the Taipei area.
Edit: I should probably answer the question... Yes, you should be able to use a Capcom IO in the same way as the TTX2. There should be a PCB next to the GPU that accepts both JVS (via USB port) and FASTIO (via ethernet port)
