Hmmm. Mine isn't, but it's power deprived. :-)
Someone with docs. on the EAE or the FPP-8 or FPP-12?

I've also played with PDP-10s, and they are also word-based machines. Not
much point in trying to define them as little- or big-endian.

Obscure note on the pdp-11: it's actually middle-endian. :-)
A 32-bit integer is stored as 3412.
(Using the FP-11 for 32-bit stuff)
