Justin,
Can you take some pics of the machine with a digital camera and post them up here? The ports should be pretty obvious. Especially the RS232, they are pretty big. So big that you might not think they are actually a port, and they also could have covers on them. My machine had only one of the covers still on it, but they are metal, and not something I would have thought would hook up to a computer if I didn't know.
The way to tell if you have a B or Bx control is to get it powered up and get the master program loaded. Once you do that and hit the operate button, you will see the coordinates displayed on the machine. You will either get three digits after the deciaml point, or four. This is in inch mode by the way, not metric. If you only get three, then you have a B, if it's four, then you have a Bx. But I am not sure that 140jodel's info is correct about not being able to run g-code with a B control. I use BobCAD to run g-code to my machine (Bx), but they also have a post processor for the KMB1, so don't give up until you know for sure.
If you can't get pics up I will put a few up for you, so you can see what things should look like. Also, CMC makes anything you would want to upgrade your machine anyway, so no matter what, you can get that thing going. You can get a tape emulator if the machine doesn't have one, that way you dont have to use that tape drive. I will take a pic of my emulator and you can see if your machine has one too, again if it doesn't you can get one.  |
