[math-fun] TJX markup/text formatter?

quad> Hello math-fun, I guess Abelson sent a friend of mine a paper in TJX format. Or maybe the text formatter was called TJX? Does anyone know what this is? Any interesting history? Apparently it's an archaic format(ter) before my time. I can't find anything on Google about it. Thanks, Robert Smith This might be the PDP10 follow-on to TJ6: people.csail.mit.edu/bkph/AIM/AIM-164A-OCR-OPT.pdf --rwg (Experiencing a flicker of brain activity from Tastebuds' Zucchini Fish.)
