Re: CFFA Run 4: Accepting pre-orders

DOS MASTER. It creates one big prodos file called dos.3.3 that holds volumes 
of dos 3.3 partitions. You can't format the volumes but it works great. 
Check out the forums at the CFFA discussion site. I even have a 16m CF image 
ready to go. It works pretty good, not perfect but good enough.
