#R:sri-arpa:-47800:wdl1:400001:000:263 wdl1!wunder May 11 15:44:00 1984 Unix system V (Release 1) apparently has a driver for a "Network Systems Corporation (NSC) A-410 processor adaptor". It is mentioned under nsc(7). As far as I know, there is no documentation beyond the five pages in the manual. Hope this helps. wunderwood
