NCR X-Station?

At swap today I picked up a neat little package made by AT&T/NCR in the early '90s. The package is 9.75W x 9D x 1.25H and looks rather like a book. The front carries only a push switch and an LED, while the rear has DB25F Parallel, RJ? and DB25F EIA, RJ? AUX, HDE15 VIDEO, and RJ? and OS/2 KEYBOARD connectors plus a concentric power input connector. There is an Intel 80C32 microcontroller, various static RAM chips, and a specialized NCR/ADDS SMD chip that pointed to X-Station information via Google. Anyone ever run across one of these critters and have any information on it? Also picked up a dual port SGX full length network card using DA15M connectors. I was intrigued by it carrying an NEC V50 PLCC chip. First I had seen. - don
