I have the computer but I'm not able to connect it to anything. There are 6 what appears to be RCA type plugs on the back, 2 wide by 3 tall, with + over one column and - over the other. What do I need to do to get this thing working? I also have an Intellec 4 that I am trying to find accessories and information for. Thanks, Jeff
