p.s. Where did you see my e-mail address? If it was a newsgroup (I think I posted an answer to comp.sys.dec.micro about some somewhat forgotten PDP families) were there any replies? It was a few days before I could get back to check it again and by then our server's had been flushed. - Aron found him here: http://www.teleport.com/~osfci/fannish.net.txt
