I said I wasn't going to try to fix this BINA-VIEW but hey... I'm on lockdown and very stir-crazy so I just went for it. Enjoy!

удивительная история 🙂 [хотя все это можно было проще сделать на 15 лампочках
Of course they couldn't have 20=0, 21=1… too easy. :p
"…obviously not gonna repair it…"
…three days later…
Its actually a very delicate device. If you change the the image (character) selects without lifting all the plates, it may bend those long select paddles and/or distort the notches in the character plates. I would put a micro controller (say an Arduino) in your control board to perform the lift/select/drop sequence without manual intervention to insure a proper sequence every time. Someone before you (or a malfunction) may have worked the display out of sequence and that may have "poped" the highest order select paddle out of position. I can see these displays being effected by humidity, temperature, smoke, and vibration (say a 100 or more units being selected at once). Too bad the manufacturer used so many "all bits on" plates… some punctuation characters could have been added. : & ( ) , ' " / . just to list some.
It looks like you have the model 089 character set – possibly with the Box symbol as a custom option. It looks like 25 plates are redundant "all on". In fact, all on is not very useful, so that makes 26. I So I would have made those plates: '.{ }/_<>[ ]!@#$%&*( )' ":;`?, I am sure these were designed when ASCII was already established, so I wonder why they went with such a proprietary character assignment. Model 105 could have included: ACAMP, DCAMP, OOR (out ofrange), ERROR, and more. It may be they liked to tailor the character sets to the needs of the customer. If they had just one more select solenoid, they could have had the entire 7-bit ASCII set, even the control characters can get represented by a symbol: NL as Null for example.
You shouldn't have opened it – now the warranty is void 🧐
Yay, but I mean–YOU'VE VOIDED THE WARRANTY!
I saw an arrival/departure board made of something similar at Charles de Gaulle airport in the 90's and since the source was computerized, I wondered why the changes appeared slowly in rows of clickety-clacks. One explanation is that because of the momentary high current from the solenoids, they staggered the changes to avoid overloading the board by activating hundreds or thousands of solenoids at once.
I wonder how few of these survived the ordeal of being shipped to the customer & still worked correctly upon arrival?
Apart from an abominable viewing angle, I simply can't imagine these being reliable enough for any practical use.
increible !!!
buen canal suscrito y campanilla activada
muchas gracias por tu informacion !!!
Nice work 👌
I wonder how many fingers got in this before you Fran ?
Part 2. Yay !
“Obviously it’s something I’m not even going to try to repair.”
See, there you go. Some things aren’t nearly as hard as you might think they are.
Coolest display ever. Think of how noisy a whole bank of those would be, yikes!
great
