Humm, I just tested it with a recent version of Merlin 8 here, and it seems
that the DOS 3.3 INIT command has been deactivated by the Merlin assembler
in order for the ASSEM new command to work under DOS 3.3.
Therefore, the remaining options you have is either to use the ProDOS 8
version of Merlin 8, to initialize the disk with a ProDOS 8 utility, and
then under Merlin 8 for ProDOS, to type the D command (for disk): "PFX=2"
(assuming the newly initialized disk is in drive 2) and then to catalog the
disk. Or just type in the "=1" or "=2" whjen prompted to enter a pathname to
catalog or simply copy the files under Mac OS X.
In case you are looking for a workable Merlin version (ProDOS 8 v2.55 which
is not the latest), a URL to download from is
http://bgilon.free.fr/apple2/P8Merlin_ZBrun.do

HTHATS,
Benoît
