When I sent the TOP disks (3 1/2", high density) to the developer I mentioned
earlier, he couldn't read them.  Turned out that his TOS and SCT were set to 33
sectors per track.  Using 'moded' (more on that later) he was able to change
his descriptor and read the disks. At the Atlanta CoCo fest, I asked Kevin
Pease about the selection of 33 sectors.  He said he had experienced some
problems with 34 sectors so he backed off.  It was hectic there and we were not
able to continued our discussions.  This is one of the subjects the consortium
should discuss.

OS9/68000 comes with a utility called 'moded'.  This utility allows the user to
make or change a device descriptor easily.  Thus, you can have any number of
descriptors for a given drive.  For a quick or temporary change, a pd utility
called 'dmode' is available to change the device descriptor 'on the fly'.  This
utility is also available under LII so you may be familiar with it.

I'm sorry I couldn't give you a simple yes or no answer.  To repeat, I can't
speak for IMS and I don't have a MM/1 so I can't test it.  I don't know of
anyone who has run tests on both machines.  So, I've tried to answer as
accurately and completely as I can.
