> Manual formatters still send, even today, TTY Model 37 style input from 1969 to the manual pager Thanks, you are perfectly right. What I found charming was that the 3E pipe.2 manual page contains «word^H^H^H^H____» written out by hand in the roff _source_. The 4E one switched to using ".it word" instead. https://minnie.tuhs.org/cgi-bin/utree.pl?file=V3/man/man2/pipe.2 https://minnie.tuhs.org/cgi-bin/utree.pl?file=V3/man/man2/pi... Another charming little quirk: the 6E kernel's falloc() does «printf("no files\n")» if it fails to find a free file structure.
