A 1403 was in use at UBC for undergrad batch services up till the end of that
service in 1979/80.
I used to get a kick out of pushing the button to raise the cabinet shroud. The
big shroud would rattle and shake as the motor-chain drive raised it to expose
the print mechanism, all while it continued to print, and the noise level would
go up by some tens of db.
At least I presume it was a 1403, it looked like just like this:
