Another rare orphan display from IEE that sought to offer an affordable (and possible) option for a digital display that looks like it's LED but is in fact incandescent. A fraction of the power requirements of what an LED equivalent would have been in the mid-70's, but strangely designed to be non-serviceable. A brief stop-gap measure on the way to cheap high brightness LED displays that came a decade later. Enjoy!

    What are you going to use it for?

    The thing I find odd about this display is that the mounting holes are ether side rather than above and below, they would have quite the gap between digits when used in multiples.

    Have you considered doing a wall of all these different numeric displays? Like an art installation or something.

    Hey, it's Fran at the bench, soldering stuff just like in the good old times! Haha. That's the ethyl alcohol.
    These displays are cute and quirky, but not as beautiful as numitrons… but at least a bit serviceable if you really need to.

    IEE for SMIEEE 😀

    A ULN2803 or ULN200x would be perfect for driving those using modern logic chips etc
