I used to be an operator (admin), for the 2200, I forgot the application it ran but I think it was some kind of billing and it would dial out to get/receive data. It was a very nice machine, the application was written in Wang Basic. But I had a copy of their IN/ix 16 bit UNIx that ran on their PCs, being a dummy I tossed the hardware when I moved many years ago :(
