Hello Newton Users, I have a question I'm hoping someone can help me with. What type of connector is at the top of the Newton 2100 next to the power adapter? I was surprised when I got and found it did not have a serial connection. I've been beaming my software packages from my 120 to the 2100, but there must be a better way and I'm guessing it has to do with the connection in question. Thanks in advance for any help you can offer.
