Those are the LED readouts with the built in decoder/latch and maybe counter?

If this is something you are building, the obvious solution is to use something else. They were neat devices because of the density, but they were always costly, and I don't think they saw all that much use. It might have been tedious to wire up all the individual ICs, but the individual ICs were certainly cheap.

The actual function is easy to get, even if you won't get that small a replacement solution.

If this is to repair something using them, replacing with a workalike will be problematic, but it may still be the best solution. It will be tough to figure out how you can work multiple ICs into where one display fits, and even get the display and a means of extending the pins to a daughter board (where you'd keep the actual decoder/latch and maybe counter), but the replacement circuitry will be straightforward.

That's the good thing about those displays. They were pretty much the equivalent of standard TTL ICs, so replacing them will be easy.
