; Modified by Tom Charlesworth:
; . Fixed so it can be assembled by a65 v1.06
; . Updated so it can be assembled by ACME 0.96.4
; . Fixed so that ProDOS entrypoint is $c70a (26 Dev 2007) (Bug #12723)
; . Modified to support Apple Oasis' entrypoint: $c761 (8 Sept 2012) (Feature #5557)
; . Added support for SmartPort entrypoint (20 Oct 2012)
; - EG. "Prince of Persia (Original 3.5 floppy for IIc+).2mg"
; . GH#370 (Robert Hoem, 27 Oct 2016):
. Added a check against open-apple during boot to route boot to slot 6
. This happens after the first two blocks are loaded from the HD.
