; If original disk loads boot1 into $3700 (and expects the RWTS at $3800),
; we let Standard Delivery load boot1+RWTS+DOS and patch boot1 here so it
; doesn't try to call the RWTS itself. Boot1 will exit via the standard
; relocation routine at $1B03, after which both RWTS and DOS will be
; in higher memory.
;
; This will all fail horribly if the relocation routine decides not to
; relocate (on old Apple II machines with less than 48K), and I have made
; peace with that.
