 It was slow, but it did proper 80 column across the top. 
I don't know if that feature was standard for all 029s, but I saw it
on every one that I used.  You could tell what someone was up to when
you saw an 029 with a hopper full of cards sitting unattended going
"rattle-rattle-rattle....rattle, ker-chunk" over and over again.
