The biggest problem is likely not to be the age of the film — I've successfully shot B&W film that was a few years older — but rather the process it was intended to be developed with.
Given the "Process by" date, it's probably either E-2 or E-3, which are incompatible with modern processing machines due to the differences in temperatures. E-2/E-3 would have been processed at around 24C, while E-6 is processed at around 38C and C-41 at 39C. As such, you can't cross-process them at a lab & any development would have to be done at home. (Or you can pay through the nose & hope one of the specialized processing labs can get something off it.)
Now, your most likely bet would be processing it as black & white. Ektachrome processes prior to E-6 actually began with creating a B&W negative using standard B&W development, followed by reversing the image & activating the colour dyes, so this isn't really that far out there. No idea what the times would be, but I've seen suggestions that stand developing in Rodinal should work. (But then, when isn't Rodinal recommended as a possibility?
)
As for colour processing: I would have thought that would be right out, but apparently not — at least one person has managed to successfully
cross-process E-2 Ektachrome in a home C-41 kit. The trick appears to be lowering the temperature and extending the development time accordingly.
