I'm looking for the manuals for Network Systems Corporation "Security Router". I am most interested in the section describing the Packet Control Facility (PCF). I need the edition published prior to 10/1994 (most likely edition 1.0 or 2.0). Possible bounty ($$$) involved ;) Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
