For some reason, people insist on calling a CRT with an amber phosphor a green screen. IBM probably had color devices for the military or for process control before the 3279, but I know of no commercial color CRT terminal before it.
IBM had color support for DIDOCS, ISPF and XEDIT pretty early. I don't recall when GDDM picked up color support. -- Shmuel (Seymour J.)

For me it was "always" colorful, because I started with colorful CRT display. However it raises question: when the colours were introduced? I mean ISPF, but it can be any other application, like MVS console or z/VM XEDIT, whatever. Note: colourful applications may work fine with monochrome displays, so it is not the question "when you started using colorful CRT". Any clue? -- Radoslaw Skorupka (looking for new job) Lodz, Poland ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
