<The idea was that a VAX*station* would have a primary user and would only <get a two user license (one for the serial port on the back, presumably <for emergencies) and a MicroVAX 2000 would have many users, possibly on <the rare and optional 8-port serial expansion, possibly on a terminal serve <This way, you could get more money for the same software on the assumption <that more potential users means more latitude to charge for software. your forgot the 3 port adaptor, maybe you meant that. they are uncommon but rare is not quite true. With that adaptor you have 3 MMJ serial ports and the already present 25pin comm serial. I have one and it's handy. Allison
