Questions and Answers

  • Question: How would I use this with the ZXpand+? Does it have a connector on the back to connect the ZXpand+?

    Posted by r***g (0) - 09/08/2020  15:13:00

    Answer: Works perfectly with the ZXpand+ . The interface has a passthrough connector and you connect the ZXpand on behind it.
