I remember writing the manual for the electronic device I had designed on our 8k 8/i using the asr-33 teletype. We had no other text display, so that was the output display as well. I can't remember any more how I edited it after first typing it. We did have a fixed head disk unit, and I must have stored it there, but it's been too long...
