what is the UFD.. PNY?
Michal has it, number 84 but no pinout. may be able to develop it if they have the donor.

Yes PNY, yes divining rod (lol)
Michal doesn't have a donor or the pinout

My "method" is highly subjective but in the end once the pinout is solved it makes sense.. sort of like a like a murder psychic, if only you saw the clues you would have seen i'm correct..

All joking aside it's pretty good at differentiating the data bus from other signals.. once that's done you can "guess" what signals are CE's or WE, RE, CLE, ALE, sometimes all of the above. If you want to get
REALLY precise you can differentiate between CE's ... group, WE, RE, CLE, and ALE (sometimes RE is an outlier though) but its very difficult and the values generally only make sense once the pin-out is solved. It's a tool, not a solution.. that's all.
Also RB and LED are always outliers.. If I had to guess I'd say Brown is R/B..
