Mary, I should have stuck with minicomputers and timesharing networks that were prevalent in the early 1970's before netware, ethernet, token ring, etc. Even with this you are remembering incorrectly. CRT's existed, but only in labs. At that time, most computer input was via punched cards and interactive was primarily teletype. Later in the 70's the venerable 'Green Screen' IBM terminals and their minicomputer counterparts took off. The big seller in the terminal era for the mini's was the vt-100 and it was introduced in 1978. The first CRT (or glass teletype) was the VT-52 introduced in 1974. IBM's 3270 display was introduced a year later. All of these terminals were fixed font. So how did the electronic typesetters work? Trial and error - an expert put it together and test printed - and repeated until he liked the result. Then he published. Thats why it was only used with books or manuals (needing many copies). CB remarked on some cheaper mechanical typesetters. However none of these did the MS Times Roman True Type font, a trade marked font, registered in the late 1980's. John
