The connector is called (by DEC) a "MMJ plug" and they're available through big electronics distributors (such as http://www.digikey.com/ and http://www.mouser.com/ ). If you don't want to spend the bucks on a bag of MMJ plugs and a MMJ crimper, I also sell complete MMJ cable assemblies. The most popular ones are MMJ to DB25F for connection to a terminal and MMJ to DB9F for connection to a PC-clone's serial port. See http://www.trailing-edge.com/www/mmj.html for ordering information. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
