I just got an old bridgeport that has a dynapath system 10 controller on it. The controller is in good shape, everything seems to be functioning correctly, and someone at some point had replaced all the membrane switches on the panel with pushbutton switches (which I agree are way better). What is the best source of info for an old controller like this? Trial and error has gotten me pretty far so far, but I don't have any documentation and trying to upload a part program is a little scary. I don't think I need a full manual, but I can't find much discussion of these controllers online. Is it because people that have them know how to use them already, and no one else is having to figure them out because they are so old? If someone has a system 10 and could give me a few pointers, I'd really appreciate it. Another thought I had the other day was to just upgrade to a newer controller and be done with it. I'm not sure if its worth the hassle. So if anyone is interested I'd be willing to sell it. I'd sell the old MSI amplifiers too if you are interested. Let me know. Thanks.
