Yes it will, but not with exactly the same result; the original doesn't
clear address 0 (it clears 255 bytes of zero page). Your method will clear
address 0, clearing all of zero page, which is more correct anyway :)
I don't have the original email handy, but I hope somewhere there the stack
pointer was setup!!
I wrote an efficient startup section some time back, on stella - time to
look it up!
