I believe this was the Floating Instruction Set on the PDP 11/35.Heh. I have a vague half-memory of _some_ box that stored the two 4-byte "words" in an IEEE double in one order, but the bytes within each word in the opposite order. It's always something ...
The fact that it's still remembered 30 years later shows how unusual it was.
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 first).
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:-)
