Voila:
+ *   Ericsson Information Systems/Nokia Data/ICL, SAD 8852 IBM 3270/5250 terminal emulation adapter
+ *
+ * This board is a terminal adapter for AT class PC machines to be connected as a terminal to
+ * IBM mainframes. There are two on board connectors, a BNC connector to act as a 3270 terminal
+ * and a twinax connector for the older 5250 terminal.
+ *
+ * The original design was probably done by the Alfaskop division at Ericsson Information Systems (EIS)
+ * The Alfaskop division was aquired by Ericsson from Datasaab AB in 1980 who was very successful selling
+ * IBM compatible terminals at strict 10% below IBM list price, whatever that was, usually quite high.
+ * The Ericsson PC AT WS286, their first 16 bit PC, was introduced 1986 and as the SAD8852 card is a 16 bit
+ * ISA card it is likelly to have been designed for the launch as Ericsson targeted the office market only.
+ * EIS was aquired by the Nokia Data division in 1988 which in turn was aquired by ICL 1991 and the terminal
+ * division by Wyse 1996. Firmware confirms 1987 as copyrigt date which fits the WS286 time line well.
