Not all Apple IIe systems support the mini assembler; only Apple IIe systems
with the enhanced ROMs contain the mini assembler routines. (To reach this
routine, type an "!" and return from the monitor.)
The enhanced ROMs starting shipping in Apple IIe systems in mid-1985.
The only supported list of monitor entry points for the Apple IIe may be found
in the "Apple IIe Technical Reference Manual".
