Many of the Canon SLR camera will Blink "ISO" constantly if they can't read the the DX code. Some models will stop blinking if you set an ISO, but some won't.
I would love to see a fresh source of Reloadable Cassettes, but with DX codes. I have a bunch of non-coded Ilford (and Agfa) cassettes from over the years which I have put away because the darn Canon does not like to not find the code. The older ones were MUCH better Physically than the DX coded ones of the same general design sold over the last few years. (and those appear to be non longer available)
You can modify unmarked cassettes by scratching off the paint to match codes, or buy some self-adhesive aluminum tape (used for sealing ductwork) at a hardware store. Porter's Camera Store sold self-adhesive DX-coded labels, but now they're closing, I don't know of another source.

I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
