Emax

I overcame my problems.

Key info here:
if you are going to use external zip drive, you want the Emax PLUS OS  
1.0 software. This allows external scsi to work.
Go to an OLD PC (like a 200MHZ or something) to make the floppy.

That is what worked for me.

If the floppy starts and does the 3 clicks, the floppy controller is  
fine. The floppy controller chip is a WD1772, it is available on the  
web, but I really don't think that is your problem.

Failing that, you will have to have someone send you a floppy for the  
$5.....
