until it bit the dust, i used an old Nak to transcribe onto digital, that was the extent of me playing my old tapes.
But no-one is doing so, all new cassette decks either have no noise reduction, or have a rudimentary version for playback only which has no settings for B/C/S it's just on or off.

It's a moot point though given the only new transport mechanism available is the Tanashin which is dreadful. Doesn't really matter whether it has noise reduction or not, it will still sound awful.
Theres an optimist. Well Ive heard of a Tanashin transport now sadly I know what it means...
Im not sure regarding the above about dolby NR
If the patents are expired it would be implemented in the new cassette decks. Why not?
This is because Dolby B is the only format used for commercially sold tapes. Tapes in the others could be had only be recording them yourself.
Also, Dolby C and Dolby S could be played back without much error on a Dolby B player.
The Dolby C and S circuitry costs a lot more than the Dolby B circuitry.
An excellent alternative to Dolby was the "Hush" noise reduction system. It was released rather late in the game but provided the same 10dB improvement in signal to noise as Dolby B, and without any pre-encoding of the input signal. Rocktron for one produced a lot of equipment using it. My Rocktron automotive Circle Surround decoder has Hush NR built in. It was obviously included because cassettes were still the predominant music source at that time. It's rather cool that you can switch it in and out on a quiet source such as FM radio or CD and hear no difference in sound quality, try that with Dolby B which requires carefully calibrated record and playback levels to avoid an audible reduction in treble response. I built myself a four channel version but seldom used it, now with digital techniques you can easily apply noise reduction via software.This is because Dolby B is the only format used for commercially sold tapes.

Yes it was called ANRS (Automatic Noise Reduction System). It was used in the CD-4 system for as well to reduce noise of the difference signals.JVC also had their own noise reduction system on their cassette decks as I recall going from memory. Seemed to work like Dolby B
I had one of these. Nice deck. But big and cumbersome. At the end of the day, I sold it as I had ( still have ) some Naks - a Dragon, a CR-7A and a ZX-9.
The 1000ZXL did not make the SAL ( spouse approval list ) . hrumph
