I think it was actually "logical", because all PDP-11s (there were 2 or 
3 FPU instructionsets/architecture in the family IIRC) stored 32 bit 
integers in middle-endian (high-order word first, but low-order byte 

But note that neither of the PDP-11 FPUs were IEEE, that was a much 
later invention. At least, I didn't come across it until much later:-)
