I just looked at 5th Edition:

-rw-r--r--  0 3      1        7998 Nov 27  1974 ./usr/source/s1/ed1.s
-rw-r--r--  0 3      1        5757 Nov 27  1974 ./usr/source/s1/ed2.s
-rw-r--r--  0 3      1        4616 Nov 27  1974 ./usr/source/s1/ed3.s

which means that we do have "ed" in assembly format, and given that Doug
found "ed3.s", we have a basis for comparison, which means we might be
able to revert 5e ed1.s and ed2.s back to what runs on the 1st Edition kernel.
