[Offer] Microsoft File 1.04 for Macintosh - copy protected (SCP, DC42, MOOF, A2R, IMG) [3.5" 800K]
Microsoft File 1.04 for Macintosh
The disk contains 2 bad sectors and is copy protected. Does anyone know how to run it on an emulator ? I tried on Mini Vmac but I can't open a raw format file, it accepts only IMG format, which doesn't work.
I have enclosed images in DC42 as well as raw images in SCP, MOOF and A2R format.

The Mac floppy controller made it possible to do some wacky things with disks.
pfi "scpimage.scp" disk1.pfi
pfi disk1.pfi -c 0-79 -p set-rpm-mac-500 -r 500000 -p decode pri disk1.pri
pri disk1.pri -p auto-align-gcr -p decode gcr disk1.psi -f -v
psi disk1.psi disk1.img
psi disk1.psi -L > disk1.txt
But I normally use a more complicated way that gives me more control over the revolutions on each track.
Note that with SCP you need to make sure you read Mac disks with at least three revolutions, otherwise the PCE tools may give random decoding errors due to how the tracks are not index aligned.
pfi disk1.pfi -c 0-79 -R 2 -p set-rpm-mac-500 -r 500000 -p decode pri disk1.pri

Is there information posted about this "PACE" copy protection somewhere? I'd like to read up on it.
One track is written so that it is read with random sync error (maybe some kind of weak bit?)
