Seems to me I remember something about that, but do not remember whether 
I kept the info. You say the the artical explained how to do it, so, what 
did it tell??  Did it mention the name of the program in question??

There is a program, called OZDOS.SHK, which when processed by UNSHRINK 
will set up a 3.5 disk as two 400K DOS disks volumes. Included are 
several utility programs. The special FID program is used to copy files 
from other DOS disks to the 3.5 disk. I am not certain whether all DOS 
3.3 programs are compatable, especially those which make calls to the DOS 
entry points (which may be not the same in the modified version). The 3.5 
disk is bootable, and from my limited experiments seems to work fine. 
But, programs operating in DOS 3.3 or ProDOS can not access that disk. 
That is why the special utilities are provided.

If OZDOS can not be found on the net, and if anyone is interested in it, 
I can convert it with binscii and place it on my home server available 
for anonymous ftp for a limited time.
