Big Blue Reader 128 v1.1 (1986) by Mike Miller of s.o.g.w.a.p. is a utility for the Commodore 128 & 1571 floppy drive to move data between a DOS floppy and a Commodore formatted floppy.  This is an early version and didn't support the 1581 yet because that wasn't released until 1987.  If anyone has a manual for the first release and wants to share, please reach out via this "Contact Us" link.  I'd love to  know what the actual capabilities of this version were.

Did you know that s.og.w.a.p. stands for "Son of God With all the Power"?  True fact.  There is usually a whole chapter of the Bible included with BBR.
