At Hopkins we had a KSR37 which had the big ol’ NEWLINE key and did 
stuff with the ESC 8 and 9 stuff that nroff spewed directly.   It even 
had a greek box that was well integrated into eqn.

It largely got supplanted with the faster and nicer printing diablo and 
even that fell to the versatec troff emulators and eventually to things 
like the Imagen laser printers.

I procured my own Model 37 from the Rocky Flats Nuclear Site surplus 
department.   It had a big sidecar paper tape punch reader.
