Not quite computer tech but I figure this is the best place to ask: Does anyone recognize the display tech that was used on the Concorde's in-cabin display? Examples: https://samchui.com/wp-content/uploads/2016/02/CON15.jpg https://samchui.com/wp-content/uploads/2016/02/CON16.jpg The display had fully-formed digits and letters, and showed either Mach and Feet, or Temp and MPH. Some pictures show the display in green and others show it in orange - which of course were popular monochrome CRT colors, yet the display looks too "flat" to be a couple CRT's. Those colors were also popular for Electroluminiscent displays which matches the evident "flatness" but I'm not sure I've seen any EL's with fully formed digits like this with no visible segmentation? I want to guess it was individual digits back-projected - which was a popular control-theater display tech at the end of the 20th century - but I can't rule out, say, really well-done edge-lit character plates. In any event there doesn't seem to be any visible jitter up and down between digits that I might expect with either of those technologies. The "FEET" display in the above-referenced JPG's shows some artifacts at the left and right edges which might be a clue? Some pics of the BA Concorde interior had a simple 15-segment and 7-segment green LED display. Don't need help with that one 🙂. Tim N3QE

I would make the same guess. They look a bit like the IEE "In line display" numeric projection displays that were popular in the 1960s. I have a couple, they are very nice high quality (very readable) numeric displays using a set of mini-projectors each with its own incandescent lamp to project a digit onto a frosted glass (or plastic) screen. https://www.industrialalchemy.org/articleview.php?item=511 The Concorde displays are not those exact units but they may well use the same technology, or perhaps even use a custom-made variant. paul

Just found this article, and apparently the old displays were replaced with the new ones shortly after the grounding in 2000/2001. This would mean they are probably LCDs. http://www.concordesst.com/returntoflight/mods.html Also, here's a photo that very clearly shows the refresh: https://www.jetphotos.com/photo/7009833

Actually, it is a "Marilake" display, built by Marilake in the UK, still in business. From what I have been able to find, they were installed in British Airways Concordes Around 1985, to replace a much less attractive 7 segment LED display. The French Concordes apparently retained the earlier LED type display. The other article is referring to a different display that replaced the Marilakes. Most of the references I have found indicate the Marilakes were Plasma displays. Nothing definitive, however. www.marilake.com/ Mark -----Original Message----- From: steven(a)malikoff.com steven--- via cctalk <cctalk(a)classiccmp.org> Sent: Saturday, September 16, 2023 9:37 PM To: General Discussion: On-Topic and Off-Topic Posts <cctalk(a)classiccmp.org> Cc: steven(a)malikoff.com steven(a)malikoff.com <steven(a)malikoff.com> Subject: [cctalk] Re: Concorde cabin display technology? Andrew said Interesting. Searching for 'Marrilite display' (I wonder what that is) turned up this page, which mentions "There was a plasma display at the front of the cabin showing the altitude, the air temperature and the current speed in both miles per hour and Mach number." https://www.heritageconcorde.com/concorde-cabin--passenger-experience
