Minux lacked a UUCP as I recall, but I'm hazy on that has Andy's crew wrote a lot of the user space. Coherent was a "full" V7 clone and include things like the dev tools including yacc/lex and was released much, much before the Taylor version came out -- so what do they use for uucp if at all? Does anyone remember any other implementations? Clem
