; Something small to put in a boot slot, so that the chain can be proved end to end.
;
; NO DATA SEGMENT, and that is not tidiness - it is the shape of what stage one can do.
; Stage one reads raw blocks into Program Memory and jumps to the first byte. It places no
; data, because it has no way to know where a payload's data ends and its code begins
; without knowing a format, and knowing a format is the thing ROM must do as little of as
; possible. So a payload either carries no initialised data or arranges its own.
;
; Which is why this prints with INIA and OUTA rather than from a string. The real stage two
; needs a Data Segment, and how it gets one is an open question written up beside this.
