APparently to book EDSAC involved climbing a flight of
stairs.
The version I heard (from MVW himself, no less) was that you had to climb
stairs between the room where you punched the tape and the room where
EDSAC itself was (and therefore where you took the tape to read it in).
After going up and down stairs a few times, he invented the idea of an
interactive debugger.
