I know of a cinema which still uses an 888 as a standalone AES/EBU to Analogue audio adaptor. I had to make a special set of cables since the fancy DCP projector has the "standard" 2xRJ45 audio output, and the Sound Processor (A Dolby CP500, which interestingly enough is a 68k system) has a DB25 input connector. A tangled mess of cables for sure, but it worked well enough that it's still going strong.
It's impressive how well these things were built and I would be surprised if there isn't going to be remaining demand for them for quite some time.
