Of course you can, though on a modern system it's no longer possible to get code into the system by toggling electrical switches, which was the way computers were bootstrapped way back in the day.
But hand assembly isn't so far away from our experience. Woz famously wrote the original Apple ][ ROM by hand, including the BASIC interpreter (itself written in a "SWEET16" bytecode for which he hand-assembled the interpreter). I don't know what the tooling looked like for that; surely he wasn't hand-toggling this thing in every time. Presumably the monitor and casette interface were written first...
