U of Calgary graduated from Marsland Teletypewriters with a big roll of newsprint and 110 bps (thus, 11 char/sec at 10 bits/byte for error correction)....to these DECs, which used the same folding-paper as big line printers for mainframes, and upped the game to 300 bps. (selectric-type print head could not move that fast, dot-matrix needed).

Then came VDTs, same stream as paper; no XY control until the PC.
