I once had to rescue a system where the root dir block was
lost. No ed. Luckily our bootrom had commands for peek/poke
& disk block IO. The v7 filesystem layout was simple enough
and I remembered enough of it that I was able to patch it
enough to bring it up and run fsck.
I'm pretty sure 'ed' was the only
editor available at that point.
I boss I used to work for insisted that we all learn "ed", because one day
it might be the only editor available to you; well, one day he was right,
when /usr on a client's box got creamed after a head crash...
