This guy looks liike he was using it like an XT but there was a lot of info window stuff if you actually used it in an ibm environment. I think that the same software protocol was used by IBM for POS systems, and other custom terminal applications. Recall that the IBM PC was a project of the terminals division of IBM. As such this is about the only example of a terminal division product which actually used it as a terminal, rather than adding the 3270 card in and running a program to get to the mainframe. I don't actually count that as a terminal division product as much as a product of the PC people. The other usage that was unique was the VM XT and VM/AT systems, which were later, much to the chagrin of the systems people. It all gets into the long sordid tale about how IBM "blew" the PC which doesnt need to be rehashed here. Jim
