Yep, I assume the change was due to change from paper teletypes to CRT terminals. 2BSD is interesting, because that would make this likely a V7/SysIII/SysV post

Yep, I assume the change was due to change from paper teletypes to CRT terminals. 2BSD is interesting, because that would make this likely a V7/SysIII/SysV poster since in 1983 they were already releasing 4.2BSD. The Unix Programming Environment was released in 1984 so that part might have confused BSD users already back when it was released! I wouldn't be surprised if AT&T continued with @ and # all the way to SVR4.
