subject: Reading H/Zenith 729K disks

Does anyone here have a copy of a utility that will run in MS-DOS or in a
DOS-VDM in OS/2 which will read the older Heath MS-DOS 5-1/4" floppy
disks that were formatted to 729K?  That's the ones which were actually
360K with the factory supplied hole re-inforcement.  Heath embarked on a
massive program to double density format and write these disks in the 1.2MB
5-1/4" floppy disk drives way back when.  I used this format with
Z-120's for years.

If you have two of the drives or a hard disk and one ..  you can copy them
to the later 5-1/4" 1.2 MB density flopppy disks or the later yet
3-1/2" 1.44/2.88 MB floppies.  I have a large stack of these I want to
move to 3-1/2" diskettes or archives.

I used to have a copy of UNIFORM which is a DOS device driver that you
could over-install in CONFIG.SYS in MS-DOS which I think would do this. 
Someone else in the UseNet forum has suggested another executable that
would run under DOS to do this.


Anyone here have a copy of such a utility?


Thanks..
