Looks like this one is mislabelled (should be N.FF):
Both are from 2003. My firmware N.IF seems to be newer. I would not want to try to downgrade unless there is a very good reason to do so.
I have noticed that EAC (as well as cachex) seems to be unable to defeat the cache.
C:\RIPZ>cachex -i -k s:
CacheExplorer 0.8 - firstname.lastname@example.org
Drive on S is ATAPI CD-RW 52X24 N.IF
[+] Buffer size: 2048 kB, read cache is enabled
[+] Supported read commands: BEh A8h(FUA) 28h(FUA) D4h(FUA) D5h(FUA) D8h(FUA)
[+] Testing cache disabling: not supported
Anyone know how to achieve success in disabling the read caching?
 -usefua seems to work with EAC for a while but it’s not long before EAC reverts to reading cache again which is easy to spot because the red blocks switch from a steady cadence to filling in the next 4 very quickly after reading once.
