Okay, I will hunt down the numbers for this.  I hope this will let me use 
either 1.44 or 720 in the same drive.

I never heard of one of these.

How about in BL4.  I don't want to include hundreds of devices just to get

But 720K floppy disks work even in pentiums, in the same drives as 1.44's.

But 486s still have these and they can read (but not write) 360K disks.
