My first tube in 1978 at TRW (ancestor of Experian) was a Raytheon wannabe. Don’t remember the model number, but it may have been a takeoff of '3270'. There was an up-down case switch, but it may have changed the display only--a real horse's ass. I haven't noticed a mention in this thread, but the clackity-clack printers we had in those days *were* upper case only. If you can find, say, ancient MACLIB'S from back in the day, all text was upper case. And punctuation marks were avoided because many printers couldn't handle them. For example,
ARE VALUES NOW EQUAL... BTW a rendition like "UCB'S" was common to distinguish plural from a singular control blocks ending in "S". I cringe now when I see "UCB's". Ungrammatical and unnecessary in up-to-date Kansas City. . .

In the monocase position it would display majscule while transmitting minucule. Inexcusable! If this was modal behavior of IBM 327x terminals it was probably one cause of the enduring bigotry against mixed case among mainframers. >From https://en.wikipedia.org/wiki/IBM_3270 I see this note: >"3270 character set" [ This set contains both lower and upper case >letters ] "On the 3275 and 3277 terminals without the a text feature, lower >case characters display as uppercase." Character generator ROMs were costly, and unavailable on interpreting keypunches. -- gil ---------------------------------------------------------------------- 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
